Administrator session compromise via stored log XSS
Published Jul 13, 2026 · Updated Jul 13, 2026
Stored XSS in Rejetto HFS 3.0.0 through 3.2.0 allows remote attackers to run script in an administrator's browser through the log viewer. The administration panel renders failed-login log entries as HTML without sanitizing the attacker-controlled username recorded in each entry. No authentication is required to plant the entry, but an administrator must view the logs; the resulting script can create accounts or invoke server-side code with administrative privileges.
