SCA: security update for mantisbt/mantisbt (GHSA-9c3j-xm6v-j7j3)

high Tenable Cloud Security Plugin ID 441752

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. In versions 2.28.1 and below, given any
 pre-existing XSS / HTML injection vulnerability, an attacker can bypass the Content Security Policy's
 script-src directive by uploading a crafted attachment to any issue that, when accessed via the
 file_download.php link, will be downloaded with a valid JavaScript MIME type resulting in script
 execution. The uploaded payload must be sniffed as a valid JavaScript MIME type by PHP finfo (see
 file_create_finfo() API function). Non-JavaScript MIME types will not get imported in a <script> tag by
 the browser, due to response header X-Content-Type-Options being set to nosniff, which requires all
 imported JavaScript files to be a valid JavaScript MIME type. This issue has been fixed in version 2.28.2.
 (CVE-2026-40597)

Solution

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