CVE-2026-102372 Details
Description
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.
A stored cross-site scripting vulnerability has been identified in GestSup versions prior to 3.2.62. The issue arises in the IMAP LOGIN connector, which fails to properly sanitize HTML email bodies. This allows unauthenticated attackers to inject arbitrary JavaScript into ticket descriptions and replies. The injected scripts are executed in the browsers of technicians, potentially leading to theft of ticket data and unauthorized actions.
Users are advised to update to GestSup version 3.2.62 or later, where this vulnerability has been patched.
