CVE-2022-0989Public exploitNetwork attack vector

Unauthenticated image proxying via unrestricted image URL

Published Apr 11, 2022 · Updated Aug 2, 2024

Content injection in NS Watermark For WooCommerce through 2.11.3 allows remote attackers to load attacker-hosted images via ns_image.php. The endpoint decodes a supplied parameter and fetches image_path and related URLs without restricting destination domains, allowing malicious content to be served through the vulnerable site. No login is required; the documented impact is content delivery and malware concealment rather than direct modification of WordPress data.
