How to fix?

There is no fixed version for Centos:8 resteasy-javadoc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream resteasy-javadoc package and not the resteasy-javadoc package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

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.
