CVE-2026-2377: Mirror-registry: quay: quay: server-side request forgery via log export functionality

A flaw was found in Red Hat Quay and mirror registry for Red Hat OpenShift. The log export feature in these products allows an authenticated user to specify an arbitrary callback URL. A backend process then makes server-side HTTP requests to this provided URL. This vulnerability, known as Server-Side Request Forgery (SSRF), could allow an attacker to send requests from the application's internal network, potentially leading to the disclosure of sensitive information.
