Advisory
Source description from Wordfence Intelligence, credited to Pedro Pinho.
The OTP Login & Register Woocommerce plugin for WordPress is vulnerable to Account Takeover in all versions up to, and including, 2.7.2. This is due to use of a client-controlled IP address (derived from spoofable request headers) as the sole key for tracking OTP attempt and send-count limits, allowing an attacker to reset those counters by changing the supplied IP value. This makes it possible for unauthenticated attackers to bypass OTP brute-force rate limiting and brute-force the short numeric one-time password to take over any account without its password.
