AI Powered Q&A
Can you explain this vulnerability to me?
The Tutor LMS Pro plugin for WordPress has an authentication bypass vulnerability in all versions up to and including 3.9.5 via its Social Login addon.
This vulnerability occurs because the plugin does not verify that the email provided in the authentication request matches the email from the validated OAuth token.
As a result, an unauthenticated attacker can log in as any existing user, including administrators, by supplying a valid OAuth token from their own account along with the victim's email address.
How can this vulnerability impact me? :
This vulnerability can have severe impacts because it allows attackers to bypass authentication and gain unauthorized access to any user account, including administrator accounts.
Such unauthorized access can lead to full control over the affected WordPress site, including the ability to modify content, steal sensitive information, or disrupt services.
The CVSS score of 9.8 indicates a critical severity with high impact on confidentiality, integrity, and availability.
