Unauthenticated cache reset via missing nonce validation
Published Jan 25, 2025 · Updated Apr 8, 2026
Cross-site request forgery in the Linear plugin for WordPress 2.8.1 and earlier allows remote attackers to reset its cache. The linear-debug request handler processes a cache-reset request without validating a WordPress nonce before altering the cached state. Exploitation requires a logged-in site administrator to activate an attacker-controlled request, and the demonstrated consequence is limited to cache reset.
