CVE-2026-107797

Status: DeferredMedium (5.3)—

Jivejdon through 5.0 contains a reflected cross-site scripting vulnerability in application/message/postThread.jsp that allows attackers to inject script via the to and tag parameters. Attackers can send crafted links to authenticated users, breaking out of unencoded inline JavaScript string literals to execute arbitrary JavaScript in the victim's session.

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).
