CVE-2026-41194 Details
Description
FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, the mailbox OAuth disconnect action is implemented as `GET /mailbox/oauth-disconnect/{id}/{in_out}/{provider}`. It removes stored OAuth metadata from the mailbox and then redirects. Because it is a GET route, no CSRF token is required and the action can be triggered cross-site against a logged-in mailbox admin. Version 1.8.215 fixes the vulnerability.
A Cross-Site Request Forgery (CSRF) vulnerability exists in FreeScout versions prior to 1.8.215, specifically within the mailbox OAuth disconnect feature. The disconnect action is performed via a GET request, which removes stored OAuth metadata and redirects the user. Because this action does not require a CSRF token, it can be exploited cross-site against an admin user of the mailbox.
Users can update to FreeScout version 1.8.215 or later, where this vulnerability has been fixed.
