TIMELINE

Oct 15 PATCH SHIPPED — CVE-2026-89058 (Red Hat RESTEasy). Fixed in Red Hat build of Quarkus 3.27.6.redhat 6.2.19.Final-redhat-00003.
Description
A flaw was found in RESTEasy's CorsFilter, which, when configured to allow all origins ("*"), reflects the request's Origin header back in the Access-Control-Allow-Origin response together with Access-Control-Allow-Credentials: true. This permissive cross-origin policy allows a malicious website to make credentialed cross-origin requests and read authenticated responses from a victim's session, resulting in a loss of confidentiality.
