Summary

MemberPress for WordPress is affected in versions up to and including 1.14.1. The save_profile_fields() function checks its nonce with an isset() condition, so omitting the nonce parameter bypasses verification, a cross-site request forgery flaw (CWE-352). An unauthenticated attacker who tricks an authenticated user into clicking a link can change that user's email address and take over the account through password reset.

Description from the CNA

The MemberPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.14.1. This is due to a bypassable nonce verification check in the save_profile_fields() function that uses an isset() condition at line 1119, allowing the security check to be completely bypassed by simply omitting the nonce parameter from the request. This makes it possible for unauthenticated attackers to change authenticated users' email addresses via a forged request granted they can trick an authenticated user into performing an action such as clicking on a link, leading to account takeover through password reset functionality.
