CVE-2026-13690: CWE-287 Improper Authentication in UsersWP
The UsersWP WordPress plugin before 1.2.67 does not validate the selected authentication provider in its two-factor login handler, allowing an attacker who already knows a user's credentials to bypass the second authentication factor and log in as that user.
AI Analysis
Technical Summary
CVE-2026-13690 is an improper authentication vulnerability (CWE-287) in the UsersWP WordPress plugin prior to version 1.2.67. The issue arises because the plugin fails to validate the selected two-factor authentication provider during login. This flaw enables an attacker with valid user credentials to bypass the second authentication factor, effectively compromising the multi-factor authentication mechanism and gaining unauthorized access to the user account.
Potential Impact
An attacker who has obtained a user's primary credentials can bypass the two-factor authentication protection and log in as that user. This undermines the security benefits of two-factor authentication, potentially leading to unauthorized access to user accounts and any associated privileges or data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor official UsersWP communications for updates and apply any released patches promptly. Until a fix is available, consider disabling two-factor authentication in UsersWP or implementing additional access controls to mitigate risk.
