AI Analysis
Technical Summary
CVE-2026-11965 is an improper authentication vulnerability (CWE-287) in the User Registration & Membership WordPress plugin prior to version 5.2.0. The flaw permits unauthenticated users who self-register through the open registration flow to obtain active paid subscriptions without payment, bypassing intended access controls for paid content.
