AI-suggested

  1. Immediately update the tigroumeow AI Engine plugin to a patched version once available; monitor vendor advisories for official fixes.
  2. If patches are not yet released, disable or restrict the REST API endpoints related to file uploads, especially rest_simpleFileUpload(), using WordPress security plugins or custom rules.
  3. Enforce strict file type validation and content scanning on all uploaded files at the web server or application firewall level.
  4. Limit user privileges rigorously, ensuring only trusted users have Subscriber-level or higher access.
  5. Monitor server logs and WordPress audit trails for unusual file upload activity or unauthorized access attempts.
  6. Implement web application firewalls (WAF) with rules to detect and block suspicious file uploads.
  7. Conduct regular security assessments and penetration testing focused on plugin vulnerabilities.
  8. Backup website data and server configurations frequently to enable rapid recovery in case of compromise.

Description

The AI Engine plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the rest_simpleFileUpload() function in versions 2.9.3 and 2.9.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server when the REST API is enabled, which may make remote code execution possible.
