CVE-2026-110268

The Post Export Import with Media plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.17.2 via the 'theme_slug' parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to perform actions on files outside of the originally intended directory. Exploitation requires the peiwm_enable_admin_download_buttons feature to be enabled in the plugin settings.
