CVE-2026-62850

5.3 mediumEPSS 0.3%

Medium (5.3) in freescout-help-desk freescout. EPSS 0.3% estimated probability of exploitation activity in the next 30 days.

On this page
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.225, the administrative tools.php maintenance endpoint is reachable without an appropriate authentication or access-control boundary. Response differences for attacker-controlled path values disclose whether arbitrary directories and files exist on the server. The same endpoint validates application-key and database-password candidates without rate limiting, per-session throttling, or a CAPTCHA, allowing unrestricted guessing attempts against application secrets. This issue is fixed in version 1.8.225.
