Settings reset via missing CSRF nonce
Published Jun 14, 2024 · Updated Mar 13, 2025
Cross-site request forgery in Similarity 3.0 and earlier allows remote attackers to reset plugin settings through an administrator's session. The plugin's settings-reset handler processes a state-changing request without validating a CSRF nonce, so the administrator's authenticated browser supplies the authority for the reset. Exploitation requires a logged-in administrator to open an attacker-controlled link or page; the documented consequence is loss of the plugin's configured settings.
