CVE-2026-11775

Summary

The User Admin Simplifier plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.0.0. This is due to missing or incorrect nonce validation on the useradminsimplifier_options_page function. This makes it possible for unauthenticated attackers to reset and permanently delete any user's stored menu and admin-bar configuration via a forged request that triggers uas_save_admin_options() and overwrites the useradminsimplifier_options database entry via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
