MantisBT has Potential Referer-Based Reflected HTML Injection / XSS in Tag Update Page
Quick fix
GHSA-6jh4-47v2-4g37 — mantisbt/mantisbt: upgrade to the fixed version with the command below.
composer require mantisbt/mantisbt:^2.28.2Details
Improper escaping of the redirection page (retrieved from the request's *Referer* header) allows an attacker to inject HTML.
While this is generally not directly actionable as modern browsers will URL-encode special characters, on some specific server configurations this could poison the cache, leading to cross-site scripting.
### Impact Cross-site scripting (XSS).
