Description

CVE-2026-62854 is a cross-site scripting (XSS) vulnerability in FreeScout versions prior to 1.8.225. It allows a user with permission to edit mailbox signatures to inject scriptable content by combining uploaded files and nested tag fragments that bypass sanitization. The malicious script executes with the victim's privileges when they open the mailbox reply editor or new-ticket page. This vulnerability is fixed in FreeScout version 1.8.225.
