WordPress · Ultimate Member · CVE-2026-93428
**Name of the Vulnerable Software and Affected Versions**
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin versions prior to 2.13.2
**Description**
An authorization bypass exists because the plugin fails to properly verify if a user is authorized to perform specific actions. Unauthenticated attackers can view privacy-restricted member profile field values, including those configured as owner-only, members-only, or role-restricted. This is achieved by querying the publicly accessible 'wp ajax nopriv um get members' endpoint. The required nonce `um-frontend-nonce` is emitted to all unauthenticated visitors via wp localize script, which removes meaningful access control and allows anonymous visitors to satisfy authentication requirements.
**Recommendations**
Update to version 2.13.2 or later.
