Jivejdon through 5.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to inject script by posting unsanitized forum message bodies. Message bodies are rendered by messageListBody.jsp with filter="false" and non-escaping default filters, executing script in the browser of every user viewing the thread.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques
