CVE-2021-4392Network attack vector

Product metadata modification via missing nonce validation

Published Jul 1, 2023 · Updated Apr 8, 2026

CSRF in impleCode eCommerce Product Catalog 2.9.43 and earlier allows remote attackers to modify product metadata through forged requests. The implecode_save_products_meta() function accepts a state-changing metadata submission without correctly validating a WordPress nonce. Exploitation requires an administrator to follow an attacker-controlled link or perform an equivalent action, after which catalog product metadata can be overwritten.
