Technical summary

The Post Export Import with Media plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.17.1 via the 'file_path' parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The vulnerability requires the attacker to upload a crafted ZIP archive containing a media_metadata.json file with path traversal sequences in the file_path field while specifying an allowed file extension for the destination filename to bypass the extension guard introduced in version 1.13.2.

Defensive priority

Administrators of WordPress installations with the Post Export Import with Media plugin should verify the plugin version and upgrade to a patched version if available. They should also monitor for suspicious activity and ensure that only authorized personnel have administrator-level access.

Recommended defensive actions

  • Verify the plugin version and upgrade to a patched version if available
  • Monitor for suspicious activity
  • Ensure that only authorized personnel have administrator-level access
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
