Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-287.

Summary

The Login & Register Forms WordPress plugin before 4.0.2 does not bind the password reset verification state to the account being reset or to the party that completed the verification, keying it instead on a value the client controls, allowing unauthenticated attackers to take over the account of any user who recently completed a reset verification, including an administrator.
