CVE-2025-13540: Qode Interactive Tiare Membership

Critical severity, CVSS 9.8. EPSS: 0.3% chance of exploitation in the next 30 days.

The Tiare Membership plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2. This is due to the 'tiare_membership_init_rest_api_register' function not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site.

Affected products

• Qode Interactive Tiare Membership: up to and including 1.2
