CVE-2025-68564Network attack vector

Unauthenticated logout via missing capability check

Published Feb 20, 2026 · Updated Feb 20, 2026

Missing authorization in Sendy 3.4.2 and earlier allows remote attackers to invoke the plugin's logout endpoint without authentication. The logout handler exposes its action without the capability check that protects privileged WordPress functions. Public sources do not disclose whether the action affects only the caller's session or the shared WooCommerce integration, so the operational scope remains unspecified.
