SCA: security update for mantisbt/mantisbt (GHSA-ggw7-9675-6v4v)

medium Tenable Self-Hosted Container Security Plugin ID 441754

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions 2.28.1 and prior are vulnerable to
 Authorization Bypass through the private issue monitoring feature . Using a crafted POST request to
 bug_monitor_add.php, a user with project-level access can add themselves as a monitor for a private issue
 they do not have access to. Despite displaying an Access Denied error, the application accepts the request
 and creates a monitor relationship for the private issue. Direct access to the private issue remains
 blocked, but the user will receive email notifications for updates, leading to disclosure of the private
 issue's metadata and content. This issue has been fixed in version 2.28.2. (CVE-2026-34579)

Solution

Update the mantisbt/mantisbt library and its related packages to version 2.28.2 or later.
