CVE-2023-39995Network attack vector

Admin-notice dismissal via missing nonce validation

Published Dec 13, 2024 · Updated Apr 28, 2026

Cross-site request forgery in Essential Plugin Portfolio and Projects 1.3.7 and earlier allows remote attackers to dismiss admin notices. The wpos_anylc_admin_init_process function accepts a forged request without valid nonce verification and performs the notice-dismissal action. Exploitation requires an administrator to interact with an attacker-controlled link, and the resulting change is limited to admin-notice state.
