CVE-2026-13598: CWE-269 Improper Privilege Management in RestrictMate
CVE-2026-13598 is a vulnerability in the RestrictMate WordPress plugin prior to version 1.3.0. It allows unauthenticated attackers to specify arbitrary user roles during account registration, enabling them to create new administrator accounts. This leads to unauthorized administrator access and potential full site takeover.
AI Analysis
Technical Summary
The RestrictMate WordPress plugin before version 1.3.0 does not properly restrict the user role parameter during account registration. This improper privilege management (CWE-269) permits unauthenticated attackers to create accounts with administrator privileges, resulting in a logged-in administrator session and full control over the affected WordPress site.
Potential Impact
An attacker can gain full administrative access to a WordPress site by creating a new administrator account without authentication. This compromises the confidentiality, integrity, and availability of the site, potentially allowing complete site takeover.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict or disable user registration functionality or apply custom code to validate and restrict user roles during registration to prevent unauthorized privilege escalation.
