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. An authenticated attacker with administrator-level access or above can 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.
Risk Assessment
An attacker with administrator privileges can read arbitrary files on the server, including configuration files containing passwords, API keys, or other sensitive data, potentially leading to further privilege escalation or data leakage. Any WordPress site running the vulnerable plugin version is at risk.
Recommendation
Update the Post Export Import with Media plugin to a version newer than 1.17.1 as soon as a fix is available, and limit administrator-level accounts to the minimum necessary.
Other vulnerabilities in Post Export Import with Media
See all- CVE-2026-104764High
The Post Export Import with Media plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 1.17.1 via deserialization of untrusted input. This allows authenticated attackers with administrator-level access and above to inject a PHP Object. No known POP chain is present in the vulnerable software, so impact only occurs if another plugin or theme with a POP chain is installed.
- CVE-2026-13430High
The Post Export Import with Media plugin for WordPress up to version 1.13.1 is vulnerable to arbitrary file upload. The issue is caused by insufficient file extension validation in the import_media_file_secure function, where the extension allow-list can be bypassed by appending a trailing dot to the filename in a ZIP archive.
