Technical details
The vulnerability is a stored cross-site scripting (XSS) flaw in the IMAP LOGIN connector's email body processing in ./core/mail.php. Unauthenticated attackers can inject arbitrary HTML and JavaScript via email messages sent to the monitored mailbox, which are stored unsanitized in ticket descriptions and replies. The injected scripts execute in technician browsers when viewing tickets, enabling session hijacking, data exfiltration, and unauthorized ticket modifications. The fix was released in version 3.2.62 (24/08/2026).
