The AdForest theme for WordPress is vulnerable to authentication bypass in all versions up to, and including, 5.1.8. This is due to the plugin not properly verifying a user's identity prior to logging them in as that user.
This makes it possible for unauthenticated attackers to authenticate as any user as long as they have configured OTP login by phone number.
Not sure which version you run? Run a passive check — it reads public files only.
Remediation & mitigations
- Update to version 5.1.9, or a newer patched version
- Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
