CVE-2024-41677

Summary

CVE-2024-41677 is a newly disclosed vulnerability affecting Qwik, a JavaScript framework known for its performance optimization. The issue lies in the framework's server-side rendering process, specifically in how Qwik handles HTML escaping. The vulnerability permits a potential mutation XSS (Cross-Site Scripting) attack. Qwik's server-side rendering converts strings according to the rules in `render-ssr.ts`, sometimes resulting in inconsistencies between the server-side and client-side DOM trees. This discrepancy can be exploited to inject malicious scripts, leading to mXSS (mutation XSS) attacks. To mitigate this risk, users are urged to upgrade to Qwik version 1.6.0 or @builder.io/qwik version 1.7.3. At present, there are no reported workarounds for this vulnerability.
