The WishList Member plugin for WordPress is vulnerable to Missing Authorization leading to Sensitive Information Disclosure and Privilege Escalation in versions up to and including 3.30.1. This is due to the missing capability checks in the 'export_settings' function. This function returns the REST API Secret Key to the attacker in the AJAX JSON response. An attacker who obtains this key can authenticate to the WishList Member API, create a new membership level assigned the administrator WordPress role, and register an arbitrary administrator-level user account, resulting in complete site takeover.
AnalysisAI
Privilege escalation in the WishList Member WordPress plugin versions up to 3.30.1 allows authenticated low-privilege users to obtain the REST API Secret Key via the unprotected 'export_settings' AJAX endpoint and leverage it to register arbitrary administrator accounts. The CVSS 8.8 (High) rating reflects full confidentiality, integrity, and availability impact, and while no public exploit is identified at time of analysis, the discovery by Wordfence - a major WordPress security vendor - typically precedes broader exploitation against the large WordPress plugin ecosystem.
