CVE-2026-34463
EPSS 0.02%MantisBT is Vulnerable to Stored HTML Injection/XSS in Clone Issue Form
描述
When cloning an issue originating from a Project other than the current one, the clone form (bug_report_page.php) prepends the source Project name before the category selector without proper escaping, allowing an attacker able to to inject HTML if they can set the Project's name (which typically requires *manager* or *administrator* access level). ### Impact Cross-site scripting (XSS). This is mitigated by Content Security Policy which restricts scripts execution. ### Patches - df22697ae497ddd93f3d9132fdf4979db8d081cd ### Workarounds Make sure Project names do not contain any HTML tags. ### Credits Thanks to Vishal Shukla for discovering and responsibly reporting the issue. The vulnerability was also identified and independently reported by @siunam321 (Tang Cheuk Hei), prior to this Advisory's publication.
