SCA: security update for mantisbt/mantisbt (GHSA-73vx-49mv-v8w5)

high Tenable Cloud Security Plugin ID 439221

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 version 2.28.0, improper escaping of tag
names retrieved from History in Timeline (my_view_page.php) allows an attacker to inject HTML and, if CSP
settings permit, achieve execution of arbitrary JavaScript, when displaying a tag that has been renamed or
deleted. Version 2.28.1 contains a patch. Workarounds include editing offending History entries (using
SQL) and wrapping `$this->tag_name` in a string_html_specialchars() call in IssueTagTimelineEvent::html().
(CVE-2026-33548)

Solution

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