CVE-2023-47870Network attack vector

Forced global logout via unprotected sign-out request

Published Nov 30, 2023 · Updated Apr 28, 2026

Cross-site request forgery in wpForo Forum 2.2.6 and earlier allows remote authenticated users to force all users to log out. The sign-out action processes a crafted request without adequate anti-CSRF and authorization checks before invalidating sessions. A logged-in attacker must induce user interaction; the consequence is session termination, and the vendor disputes exposure after 2.2.3.
