Resteasy-core: resteasy: corsfilter reflects arbitrary origin with credentials under wildcard config

Impact

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.
