CVE-2026-104764 Details
Description
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 makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
A PHP Object Injection vulnerability has been identified in the Post Export Import with Media plugin for WordPress, affecting all versions through 1.17.1. The vulnerability arises from the deserialization of untrusted input, allowing authenticated attackers with administrator-level access to inject PHP objects. While the vulnerable software does not have a known PHP Object Injection chain, the impact could be significant if another plugin or theme with such a chain is installed, potentially enabling actions like deleting files, accessing sensitive data, or executing code, depending on the specific chain available.
Users are advised to update the Post Export Import with Media plugin to version 1.17.2 or a newer patched version.
