Unauthenticated Plugin Installation via Exposed AJAX Nonce

The Vayu X WordPress theme before version 1.0.6 contains an insufficient capability check vulnerability in its AJAX actions that exposes security nonces to all authenticated users. This allows any logged-in user—including low-privilege accounts like subscribers—to install and activate arbitrary WordPress plugins from the official repository without proper authorization. This vulnerability is particularly dangerous because WordPress sites often have numerous user accounts with varying permission levels. Attackers with subscriber-level access can escalate their capabilities by installing malicious or backdoored plugins, potentially leading to complete site compromise, data exfiltration, or use of the compromised site for further attacks.

While this specific CVE shows zero matching Casky skills due to its recent discovery and lack of mapped MITRE techniques, practitioners using Casky's Claude AI-powered platform would detect related attack patterns through analysis of improper access control and privilege escalation behaviors. Security teams monitoring WordPress environments would look for suspicious AJAX requests to theme functions, unexpected plugin installations by low-privilege users, and audit logs showing capability mismatches between user roles and performed actions. Extended reasoning across Casky's 754 mapped skills would highlight the need for stronger capability validation in custom AJAX handlers and enforcement of proper WordPress nonce verification patterns—critical controls that apply across numerous WordPress security scenarios tracked in the broader skill taxonomy.
