CVE-2022-4147Network attack vector

Cross-origin request acceptance via invalid Origin handling

Published Dec 6, 2022 · Updated Apr 14, 2025

Improper authorization in Red Hat Quarkus 2 allows remote attackers to issue cross-origin GET or POST requests through the CORS filter. The Vert.x HTTP CORS filter returns 200 OK and passes simple XMLHttpRequest traffic to application handlers when the Origin value is not allowed. Exploitation requires CORS to be enabled, user interaction with attacker-controlled content, and a target endpoint whose response or state has security significance.
