Summary
MantisBT has Stored HTML Injection / XSS when displaying Tags in Timeline
Original description
The description as published by the source.
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().
