Who should care

Defenders responsible for WordPress sites using the miniOrange 2FA plugin should assess exposure and prioritize verification and potential updates. WordPress site administrators and security teams should review and update incident response plans to address potential 2FA bypass attacks. They should also monitor for potential 2FA bypass attempts and verify the version of the miniOrange 2FA plugin to ensure it is updated to 6.3.1 or later.

Why it matters

Defenders should prioritize verifying the version of the miniOrange 2FA plugin and ensuring it is updated to 6.3.1 or later to prevent potential 2FA bypass attacks. WordPress site administrators and security teams should assess exposure and take necessary actions to prevent potential attacks.

• Potential 2FA bypass attacks on WordPress sites using the miniOrange 2FA plugin
• Possible addition of unauthorized authenticators by attackers who know a user's password
• Verification of plugin version and updates to 6.3.1 or later is necessary to prevent potential attacks
• Monitoring for potential 2FA bypass attempts is recommended

Technical summary

The miniOrange 2FA WordPress plugin before 6.3.1 does not prevent a pending passkey login from registering an additional passkey on an account that already has one configured. This allows an attacker who knows a user's password to add their own authenticator and bypass the second factor. The vulnerability affects WordPress sites using the miniOrange 2FA plugin versions 6.2.9 to 6.3.0. Defenders should prioritize verifying the version of the miniOrange 2FA plugin and ensuring it is updated to 6.3.1 or later to prevent potential 2FA bypass attacks.
