MantisBT has Potential Referer-Based Reflected HTML Injection / XSS in Tag Update Page
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). ### Patches - b1ebc57763f104eb5f541b7b4d1ce6948168abd9 ### Workarounds None ### Credits Thanks to siunam (Tang Cheuk Hei) for discovering and responsibly reporting the issue.
