Deeper analysis
The PSW Front-end Login & Registration plugin for WordPress is vulnerable to privilege escalation in all versions through 1.12. The flaw resides in the customer_registration() function and stems from use of a weak, low-entropy OTP mechanism inside the forget() function (CWE-330), enabling unauthenticated attackers to trigger password resets for arbitrary accounts.
An attacker with no credentials can request a password reset for any user, including site administrators, and complete the reset to obtain full administrative control and site takeover. The vulnerability carries a CVSS 3.1 base score of 9.8 reflecting network-exploitable impact on confidentiality, integrity, and availability without authentication or user interaction.
