Advisory
Source description from Wordfence Intelligence, credited to Erwan LR.
The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 6.24.1. This is due to missing or incorrect nonce validation on the 'discard' case in the mooauth_client_applist_page function. This makes it possible for unauthenticated attackers to make changes to the configured apps via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
