Summary

MantisBT has Stored HTML Injection/XSS when displaying Tags in Timeline

Details

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.

Impact

Cross-site scripting (XSS).

Patches

f32787c14d4518476fe7f05f992dbfe6eaccd815

Workarounds

Edit offending History entries (using SQL)
Wrap $this->tag_name in a string_html_specialchars() call in IssueTagTimelineEvent::html()
