CVE-2025-13737 Details
Description
The Nextend Social Login and Register plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.21.

This makes it possible for unauthenticated attackers to unlink the user's social login via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Nextend Social Login and Register plugin for WordPress, affecting all versions through 3.1.21.

Users are advised to update the Nextend Social Login and Register plugin to version 3.1.22 or later.
