GestSup versions before 3.2.61 fail to properly sanitize HTML email bodies in the IMAP LOGIN connector, allowing unauthenticated attackers to store arbitrary JavaScript in ticket descriptions and replies. Attackers can send emails to the monitored mailbox containing script tags and event handlers that execute in technician browsers, enabling ticket data theft and unauthorized actions.
