Description
The WP 2FA plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.2.1 due to the use of a linear-time comparison operator when comparing token hashes. This allows an attacker to gain information about authentication tokens by observing small time differences in server response times. This is a vulnerability that is generally not realistically exploitable over the internet due to other factors that will have a greater influence on response times.
