CVE, Research URL: CVE-2026-19423
Home page URL: Security reports for Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin
Application: Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin
Published on: Aug 28, 2026
Research Description: The Ultimate Member WordPress plugin before 2.13.0 does not validate a submitted role selection when it cannot resolve the set of roles a profile form permits, and screens the value against the site's registered role names rather than against the form's own allow-list, allowing unauthenticated users who register through the Ultimate Member WordPress plugin before 2.13.0's own form to grant themselves arbitrary capabilities and reach administrator-equivalent access.
Affected versions: max 2.13.0.
Status: vulnerable
