OAuth Single Sign On – SSO (OAuth Client) <= 6.26.3 - Authentication Bypass

Published Dec 12, 2024 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 6.26.3. This is due to insufficient verification on the user being returned by the social login token. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username and the user does not have an already-existing account for the service returning the token.
