Researcher István Márton - Wordfence

Description

The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on multiple AJAX functions in versions up to, and including, 6.23.3. This makes it possible for authenticated attackers with subscriber-level permissions to modify the plugin's settings, which could potentially be used to achieve privilege escalation.
