Auth bypass in Login & Register Forms

CVE-2026-14836

The Login & Register Forms WordPress plugin before 3.2.5 does not properly enforce the rate limit on its password-reset verification-code flow, keying both the verification code and the per-source attempt counter on an unauthenticated, client-controlled value, allowing unauthenticated attackers to reset the limit at will and brute-force the code to take over any account, including administrators, when the verification-code reset mode is enabled.
