CVE-2026-66599 Aug 24, 11:39 HIGH This Week

Unauthenticated cross-site scripting in the WPComplete WordPress plugin (versions up to and including 2.9.5.6) allows remote attackers to inject and execute arbitrary JavaScript in the context of another user's browser session, with scope change indicating the payload crosses the plugin's security boundary to affect authenticated users such as site administrators. The CVSS vector (PR:N/UI:R/S:C) is consistent with a stored or reflected XSS pattern where an unauthenticated attacker plants a payload that is later triggered when a privileged user visits an affected page. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
