Short explanation

The WP Libre Form WordPress plugin version 1.5.0.1 does not validate uploaded file types, allowing unauthenticated attackers to upload PHP files to a web‑accessible location and execute them, creating a critical remote code execution (RCE) risk.

Why does it matter?

Remote code execution can give attackers full control of the server, leading to data theft and service disruption.

What should be done?

  • Monitor vendor advisories for a patch and apply it when released
  • Restrict or disable file upload functionality in WP Libre Form
  • Implement a web application firewall to block PHP uploads
  • Validate uploaded file types server‑side
  • Regularly update WordPress plugins
