CVE-2026-13353Network attack vector

Subscriber-level code execution via evaluated field mappings

Published Jul 11, 2026 · Updated Jul 11, 2026

Code injection in Smackcoders Inc. WP Ultimate CSV Importer 8.0.1 and earlier allows remote authenticated users to execute server-side code. The install_addon, saveMappedFields, and StartImport AJAX handlers omit capability checks, letting crafted MappedFields PHP expressions reach eval() in ImportHelpers::get_meta_values(). Subscriber-level access and an admin-page nonce are sufficient to install the WooCommerce add-on, store an expression, and execute it in the WordPress server process.
