Technical Analysis

CVE-2026-11775 is a CSRF vulnerability in the User Admin Simplifier WordPress plugin by adamsilverstein. The issue is due to missing or incorrect nonce validation on the useradminsimplifier_options_page function, allowing unauthenticated attackers to cause an administrator to execute a forged request. This request triggers uas_save_admin_options(), overwriting the useradminsimplifier_options database entry and resulting in the reset and permanent deletion of any user's stored menu and admin-bar configuration. The vulnerability affects all versions up to and including 3.0.0.

Potential Impact

An attacker can cause a site administrator to unknowingly reset and delete stored menu and admin-bar configurations for any user by exploiting the CSRF vulnerability. This results in loss of user-specific interface customizations but does not impact confidentiality or availability. The integrity of user interface settings is compromised.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should be cautious about clicking on untrusted links while logged into WordPress with administrative privileges. Monitoring for updates from the plugin vendor or WordPress security advisories is recommended.
