CVE-2020-36754: paid memberships pro vulnerability

What is known

The Paid Memberships Pro plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.4.2. This is due to missing or incorrect nonce validation on the pmpro_page_save() function. This makes it possible for unauthenticated attackers to save pages via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Business impact

Successful exploitation of CVE-2020-36754, a medium vulnerability (CVSS 4.3) affecting paid memberships pro, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether paid memberships pro is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation.
