CVE-2020-36754Public exploitNetwork attack vector

Unauthorized page saves via missing nonce validation

Published Oct 20, 2023 · Updated Apr 8, 2026

Cross-site request forgery in Paid Memberships Pro 2.4.2 and earlier allows remote attackers to save pages through an administrator's browser. The pmpro_page_save() function accepts a page-save request without correctly validating its nonce, treating attacker-chosen input as authorized. Exploitation requires a logged-in site administrator to trigger the forged request, and the documented consequence is unauthorized page saving.
