CVE-2026-34579
MantisBT has an authorization bypass in private issue monitoring
描述
Using a crafted POST request to bug_monitor_add.php, a user with project-level access can add themselves as a monitor for a private issue they do not have access to. Despite displaying an Access Denied error, the application accepts the request and creates a monitor relationship for the private issue. ### Impact Direct access to the private issue remains blocked, but the user will receive email notifications for updates, leading to disclosure of the private issue's metadata and content. ### Patches - 0a93267deba445fb9d15250c16e6fdb1246ffa65 ### Workarounds None ### Credits Thanks to Vishal Shukla for discovering and responsibly reporting the issue.
