CVE-2026-102372 PUBLISHED

GestSup before 3.2.62 Stored XSS via Email Body in LOGIN IMAP Connector

Assigner: VulnCheck
Reserved: 28.09.2026 Published: 29.09.2026 Updated: 29.09.2026

GestSup versions before 3.2.62 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.
