CVE-2026-2376
Mirror-registry: quay: quay: server-side request forgery via open redirect vulnerability in web interface
Description

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.

CVSS 3.1 MEDIUM [email protected]
Solution
Prevent SSRF by validating all external URLs before processing redirect requests.
  • Validate all URLs accessed by the application.
  • Implement allow-lists for trusted domains.
  • Disable or restrict automatic redirect following.
  • Update mirror-registry to the latest version.
