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 OAuth metadata removal for a logged-in mailbox admin via a crafted cross-site request. This vulnerability is fixed in version 1. 8. 215.
AI Analysis
Technical Summary
CVE-2026-41194 describes a CSRF vulnerability in FreeScout's mailbox OAuth disconnect action implemented as a GET request (`GET /mailbox/oauth-disconnect/{id}/{in_out}/{provider}`). Because this route does not require a CSRF token, an attacker can cause a logged-in mailbox administrator to unknowingly remove stored OAuth metadata by tricking them into visiting a malicious site. The issue affects FreeScout versions prior to 1.8.215 and is resolved in version 1.8.215.
Potential Impact
An attacker can cause a logged-in mailbox administrator to unintentionally disconnect OAuth integrations by exploiting the CSRF vulnerability. This results in loss of stored OAuth metadata, potentially disrupting mailbox functionality. The CVSS score of 5.4 (medium severity) reflects limited impact on confidentiality but low integrity and availability impact.
Mitigation Recommendations
Upgrade FreeScout to version 1.8.215 or later, where the vulnerability is 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 channels. Patch status is not explicitly confirmed beyond the version fix note; check vendor advisory for current remediation guidance.
