CVE-2022-29230Network attack vector

Script execution via unescaped hydration payload

Published May 18, 2022 · Updated Apr 23, 2025

Cross-site scripting in Shopify Hydrogen 0.10.0 through 0.18.0 allows remote authenticated users to execute JavaScript in storefront pages. The server entry path embeds user-controlled hydration data in inline flight-data script content without safely escaping script-tag boundaries. An application must place user-controlled values in its hydration payload; injected code then runs in a storefront visitor's browser.
