CVE-2026-16036: CWE-287 Improper Authentication in miniOrange 2FA
The miniOrange 2FA WordPress plugin before 6.2.7 does not bind the second factor being configured during the pre-login two-factor challenge to the target account's existing factor, allowing an attacker who knows a user's password to rebind that user's second factor to an attacker-controlled destination, complete the challenge, and take over the account, including administrator accounts.
AI Analysis
Technical Summary
CVE-2026-16036 is an improper authentication vulnerability (CWE-287) in the miniOrange 2FA WordPress plugin prior to version 6.2.7. The vulnerability arises because the plugin does not bind the second factor configured during the pre-login two-factor challenge to the target account's existing factor. An attacker with knowledge of a user's password can exploit this to rebind the second factor to an attacker-controlled endpoint, bypass the two-factor authentication challenge, and gain full account access.
Potential Impact
An attacker who knows a user's password can bypass the intended two-factor authentication protection by rebinding the second factor to their own control. This leads to full account takeover, including accounts with administrative privileges, compromising the security of the affected WordPress site.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor the miniOrange plugin updates and apply version 6.2.7 or later once available. Until an official fix is confirmed, restrict password exposure and consider disabling the affected two-factor authentication plugin as a temporary measure.
