Improper escaping of a textarea custom field's contents in the Update Issue page (bug_update_page.php) allows an attacker to inject HTML and, if CSP settings permit, execute arbitrary JavaScript when the page is loaded. ### Impact Session theft leading to admin account takeover, full project data access. - Precondition: A textarea-type custom field must be configured for the project - Attacker: Authenticated user with bug report permission (low privilege) - Victim: Any user viewing the bug edit form, including administrators ### Patches - 5fec0f448b7a7d7d539a6adb6dccceac4e4e4ab7 ### Workarounds The default Content-Security Policy will block script execution. ### References - https://mantisbt.org/bugs/view.php?id=37003 - This is related to [CVE-2024-34081](https://github.com/advisories/GHSA-wgx7-jp56-65mq). ### Credits Thanks to the following security researchers for independently discovering and responsibly reporting the issue, and providing a patch to fix it. - Thanks to Nozomu Sasaki (Paul) (@morimori-dev) - Tristan Madani (@TristanInSec) from Talence Security
Update mantisbt/mantisbt to 2.28.2 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in composer. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
