CVE-2026-11965

User Registration & MembershipVulnerabilityCVSS 6.5

The User Registration & Membership WordPress plugin before 5.2.0 does not enforce payment completion before activating a paid membership subscription, allowing unauthenticated users (after self-registering an account through the open registration flow) to obtain an active subscription on any paid plan without paying and access the gated content.

No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.

Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution

Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.

No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
