Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in the "get_user()" parameter when it does a check based on the API key that was provided, but doesn’t verify if the key was one generated by the Give API, but rather just fetches the "user_id" for any meta key in the "wp_usermeta" table. A remote attacker can bypass authentication process and gain unauthorized access to personally identifiable user information (PII), such as names, addresses, IP addresses, and email addresses.

Mitigation
Install updates from vendor's website.
