Summary

Qwik is a performance focused javascript framework. Prior to version 1.19.0, Qwik City’s server-side request handler inconsistently interprets HTTP request headers, which can be abused by a remote attacker to circumvent form submission CSRF protections using specially crafted or multi-valued Content-Type headers. This issue has been patched in version 1.19.0.
