✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: To mitigate this issue, ensure that applications utilizing the XMLRPC-C library do not directly expose its error pages to end-users via a web browser. Configure web servers or application frontends to intercept and sanitize or replace error responses originating from XMLRPC-C before they are rendered client-side. Alternatively, restrict XMLRPC-C deployments to backend services that do not present error output in a user-facing web interface.
