WordPress Access Control <= 4.0.13 — Improper Access Control to Sensitive Information Exposure via REST API

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under WordPress Access Control.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch WordPress Access Control to get an email when the next vulnerability is published.
