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
CVE-2026-18469 is an improper authentication vulnerability (CWE-287) in the Login & Register Forms WordPress plugin versions before 4.0.2. The plugin fails to enforce password reset attempt limits against a server-derived value, instead relying on client-controlled data for both the verification code and per-source attempt counter. This design flaw allows unauthenticated attackers to reset the attempt limit arbitrarily and brute-force the verification code, potentially taking over any user account, including administrator accounts, when the verification-code reset mode is active.
Potential Impact
Successful exploitation allows an unauthenticated attacker to bypass password reset attempt limits and brute-force verification codes, leading to account takeover of any user, including administrators. This compromises confidentiality, integrity, and availability of affected accounts.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider disabling the verification-code reset mode if possible to reduce risk.
