CVE-2026-25151Network attack vector

Unauthorized state changes via Content-Type misclassification

Published Feb 3, 2026 · Updated Feb 3, 2026

CSRF in Qwik City's server-side request handler before 1.19.0 allows remote attackers to cause unauthorized state changes. The checkCSRF path skips the Origin check when header casing, comma-separated values, or an absent Content-Type causes form requests to be misclassified. Exploitation requires victim interaction and a successful CORS preflight; impact depends on the application's CORS and cookie policies.
