Shibboleth

CVE-2026-12281 Jul 15, 06:00 HIGH POC PATCH This Week

Authentication bypass in the Shibboleth WordPress plugin before 2.5.4 lets remote unauthenticated attackers forge identity headers and log in when the HTTP header identity mode is enabled without an anti-spoofing key.

Rated CVSS 8.1 (CWE-287); publicly available exploit code exists (WPScan), but it is not listed in CISA KEV.
