Post creation and deletion via missing nonce validation
Published Jan 5, 2024 · Updated Apr 28, 2026
Cross-site request forgery in Apollo13 Framework Extensions 1.9.1 and earlier allows remote attackers to add or delete posts. The a13fe_nava_add_post and a13fe_nava_delete_post functions accept state-changing requests without valid nonce verification. Exploitation requires an administrator with an active WordPress session to open an attacker-controlled link, after which posts can be created or removed under that administrator's authority.
