CVE-2025-13145Network attack vector

Administrator-level object injection via CSV deserialization

Published Nov 19, 2025 · Updated Nov 19, 2025

PHP object injection in WP Ultimate CSV Importer 7.33.1 and earlier allows remote authenticated users to inject objects through CSV imports. The import_single_post_as_csv function in SingleImportExport.php deserializes untrusted CSV-supplied data, enabling attacker-controlled object construction. Administrator-level access is required, and file deletion, sensitive-data retrieval, or code execution also requires a usable POP chain from an installed plugin or theme.
