Settings modification via missing nonce validation
Published Sep 27, 2025 · Updated Sep 27, 2025
Cross-site request forgery in Funnnny HidePost 2.3.8 and earlier allows remote attackers to modify plugin settings through a forged request. The options.php settings handler accepts state-changing parameters without validating a WordPress nonce before saving them. Exploitation requires an administrator with an authenticated WordPress session to perform an attacker-induced action, such as following a link; the established consequence is limited to unauthorized plugin-setting changes.
