WP 2FA <= 2.2.1 - Time-Based TOTP attack to Sensitive Information Exposure
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.
