Description

The Web3 WordPress plugin before 3.0.0 is vulnerable to an authentication bypass due to incorrect authentication checking in the login flow in functions 'handle_auth_request' and 'hadle_login_request'. This makes it possible for non authenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username.

Affected products

Web3: before 3.0.0 — fixed in 3.0.0

How to fix

Upgrade to a fixed version: Web3 3.0.0. Check the vendor advisory for mitigations.
