CVE-2022-26144
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn XSS issue was discovered in MantisBT before 2.25.3. Improper escaping of a Plugin name allows execution of arbitrary code (if CSP allows it) in manage_plugin_page.php and manage_plugin_uninstall.php when a crafted plugin is installed.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCross-site scripting (XSS) vulnerability in MantisBT before version 2.25.3 allows attackers to inject malicious JavaScript code through improperly escaped plugin names displayed in manage_plugin_page.php and manage_plugin_uninstall.php. When a crafted plugin is installed, the plugin name is rendered without proper sanitization, enabling arbitrary script execution in victim browsers (mitigated by Content Security Policy).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify MantisBT installation versionAccess the admin page or check the config file (config.php) for the version number, or view the footer of MantisBT pages which typically displays the versionAffected if The installed version is any release before 2.25.3 (e.g., 2.25.0, 2.25.1, 2.25.2, or earlier)
-
Confirm access to plugin management pagesNavigate to manage_plugin_page.php and manage_plugin_uninstall.php through the MantisBT web interface (typically at /manage_plugin_page.php and /manage_plugin_uninstall.php under the MantisBT root URL)Affected if These pages are accessible without authentication bypass or the server responds to these endpoints
-
Check for untrusted or unknown pluginsReview the installed plugins list in the plugin management interface - look for any plugins with unusual names, recently added plugins, or plugins you did not intentionally installAffected if Any plugin is installed with a name containing special characters (such as <script>, javascript:, or other XSS vectors) that could execute in the browser
You are affected if your MantisBT version is below 2.25.3 AND you have any plugin installed, particularly one with a crafted name that could trigger XSS when viewing the plugin management pages.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.25.3
Upgrade to MantisBT 2.25.3 or later which implements proper escaping of plugin names. Until patched, ensure Content Security Policy headers are properly configured to mitigate XSS attacks.
2.25.3
- 1. Backup your MantisBT database and files before proceeding with any upgrade
- 2. Download MantisBT version 2.25.3 or later from the official mantisbt.org repository
- 3. Extract the new version files to a temporary location
- 4. Copy the config/config_inc.php file from your existing installation to preserve your database credentials and settings
- 5. Replace the existing MantisBT installation files with the new version files, preserving your configuration
- 6. Verify the manage_plugin_page.php and manage_plugin_uninstall.php files have been updated to include proper escaping of plugin names
- 7. Clear any caches if your installation uses caching
- 8. Test that you can access the Manage Plugins page without errors
