CVE-2026-41904: Freescout-Help-Desk Freescout

High severity, CVSS 7.6. EPSS: 0.3% chance of exploitation in the next 30 days.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.217, a user with updateAutoReply permission can store an XSS payload in the mailbox auto-reply message. The payload is rendered unescaped in the auto-reply email sent to every customer who contacts the mailbox. Email clients do not enforce CSP, so the payload executes in the customer's webmail / mail-client context. This issue has been patched in version 1.8.217.
