CVE-2026-2376: Mirror-registry: quay: quay: server-side request forgery via open redirect vulnerability in web interface
A flaw was found in mirror-registry where an authenticated user can trick the system into accessing unintended internal or restricted systems by providing malicious web addresses.
When the application processes these addresses, it automatically follows redirects without verifying the final destination, allowing attackers to route requests to systems they should not have access to.
Other sources
An open redirect vulnerability was identified that allows user-controlled URLs to be supplied to backend workflows without sufficient validation. When combined with the log export callback functionality, this results in a server-side request forgery (SSRF) condition in which a backend worker performs HTTP requests to arbitrary destinations supplied by an authenticated user.
