Auth bypass in Login & Register Forms

CVE-2026-18469

The Login & Register Forms WordPress plugin before 4.0.2 does not enforce its password reset attempt limit against a server-derived value, keying both the verification code and the per-source attempt counter on client-controlled data, 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.
