CVE-2024-23841Network attack vector

Cross-site scripting via unescaped SSR transport data

Published Jan 30, 2024 · Updated Jun 17, 2025

Cross-site scripting in Apollo GraphQL @apollo/client-integration-nextjs before 0.7.0 allows remote attackers to execute JavaScript. The transportDataToJS function embeds serialized GraphQL data directly in an SSR script without escaping HTML-significant characters. Exploitation requires attacker-controlled input from a crafted link or GraphQL response to reach server-side rendering, after which injected script runs in the rendered page.
