DescriptionCVE.org

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.

AnalysisAI

Account takeover in the Login & Register Forms WordPress plugin (versions before 3.2.5) enables unauthenticated attackers to brute-force password-reset verification codes by bypassing the plugin's rate-limit control. The rate limiter and code storage are both keyed on a client-supplied value, meaning an attacker can arbitrarily reset their attempt counter and exhaust the verification code space, resulting in full compromise of any account - including site administrators - on affected WordPress installations. …

Vulnerability AssessmentAI

Exploitation	The Login & Register Forms plugin's verification-code-based password reset mode must be explicitly enabled in the plugin settings - this is a non-default configuration distinct from the standard WordPress core password reset mechanism, and this is reflected in the CVSS AC:H rating. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The NVD CVSS score of 8.1 (High) with vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H is reasonable: AC:H correctly reflects that the vulnerable code path requires the non-default verification-code reset mode to be enabled, reducing the exposed population. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An unauthenticated attacker targets a WordPress site running the Login & Register Forms plugin with verification-code reset mode enabled, initiating a password reset for a known administrator account. By cycling the client-controlled key value after each failed attempt, the attacker continuously resets the rate-limit counter and systematically brute-forces the verification code space. …
Remediation	Update the Login & Register Forms WordPress plugin to version 3.2.5 or later, which resolves the rate-limit bypass by anchoring both the verification code and the attempt counter to a server-controlled session identifier rather than a client-supplied value. … Detailed patch versions, workarounds, and compensating controls in full report.
