CyberRota Analysis
AI-GeneratedThe WP OAuth Server plugin for WordPress versions prior to 6.4.0 is vulnerable due to improper binding of OpenID Connect identity assertions, allowing users with Subscriber roles and above to impersonate any authenticated user, including administrators. This critical vulnerability can lead to unauthorized access to applications utilizing the site for single sign-on, posing significant risks to user data and system integrity. Organizations using this plugin should prioritize immediate updates to mitigate potential exploitation.
Original NVD Description
The WP OAuth Server ( Login with WordPress ) WordPress plugin before 6.4.0 does not bind the OpenID Connect identity assertion it issues to the authorization grant being exchanged, returning instead the assertion belonging to whichever user authenticated most recently, which allows users with the Subscriber role and above to obtain a validly signed identity assertion for another user, including an administrator, and authenticate as them at any application that uses the site for single sign-on.
