CVE-2026-104763

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 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. This 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.
