Recommendation: Monitor — no exploitation signal at the moment.

FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to 1.8.3, Faction is vulnerable to stored cross-site scripting (XSS) via attachment filenames in assessment file preview flows. User-supplied filename values are persisted and later rendered into HTML/attribute contexts without output encoding, allowing attacker-controlled JavaScript to execute in the browser of any user who views the affected page. Because the payload is stored server-side and rendered to other users, exploitation is persistent and can impact privileged accounts. This vulnerability is fixed in 1.8.3.
