CVE-2026-41194: CWE-352: Cross-Site Request Forgery (CSRF) in freescout-help-desk freescout
FreeScout versions prior to 1. 8. 215 contain a Cross-Site Request Forgery (CSRF) vulnerability in the mailbox OAuth disconnect functionality. The affected endpoint uses a GET request without requiring a CSRF token, allowing an attacker to trigger the OAuth disconnect action cross-site against a logged-in mailbox admin. This vulnerability was fixed in version 1. 8. 215.
AI Analysis
Technical Summary
FreeScout, a self-hosted help desk and shared mailbox application, had a CSRF vulnerability (CWE-352) in its mailbox OAuth disconnect feature prior to version 1.8.215. The disconnect action was implemented as a GET request to the route `/mailbox/oauth-disconnect/{id}/{in_out}/{provider}` without CSRF protection. Because GET requests do not require a CSRF token, an attacker could trick a logged-in mailbox admin into unintentionally disconnecting OAuth metadata by visiting a malicious site. This issue was resolved in FreeScout version 1.8.215.
Potential Impact
The vulnerability allows an attacker to cause a logged-in mailbox administrator to unknowingly disconnect OAuth metadata from the mailbox. This could lead to denial of service or disruption of OAuth-based mailbox functionality. The CVSS score is 5.4 (medium severity), indicating limited impact primarily affecting integrity and availability without confidentiality loss.
Mitigation Recommendations
Upgrade FreeScout to version 1.8.215 or later, where this CSRF vulnerability has been fixed by requiring proper CSRF protection on the OAuth disconnect endpoint. Since no official patch link or advisory is provided, users should verify the version upgrade from the vendor's official release notes or repository. Patch status is not yet confirmed via vendor advisory; check the vendor's official channels for current remediation guidance.
