CVE-2026-18469: CWE-287 Improper Authentication in Login & Register Forms
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.
AI Analysis
Technical Summary
The Login & Register Forms WordPress plugin before version 4.0.2 contains an improper authentication vulnerability (CWE-287) where password reset attempt limits are not enforced against server-derived values. Instead, both the verification code and per-source attempt counter are keyed on client-controlled data, enabling unauthenticated attackers to reset the limit at will. This allows brute-force attacks on the verification code, potentially leading to account takeover of any user, including administrators, when the verification-code reset mode is active.
Potential Impact
An attacker can bypass password reset attempt limits and brute-force verification codes to reset passwords and take over user accounts, including those with administrative privileges. This compromises the confidentiality and integrity of user accounts on affected WordPress sites.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider disabling the verification-code reset mode or restricting access to the password reset functionality to trusted users only.
