CVE-2024-12313Network attack vector

PHP object injection via crafted cookie deserialization

Published Jan 7, 2025 · Updated Apr 8, 2026

PHP object injection in Compare Products for WooCommerce 3.2.1 and earlier allows remote attackers to inject PHP objects via a crafted cookie. Cookie-handling code in classes/class-wc-compare-functions.php passes the untrusted woo_compare_list value to PHP deserialization without restricting object creation. A usable POP chain from another installed plugin or theme is required; with one present, object injection enables arbitrary file deletion, sensitive-data access, or code execution.
