Technical details
The vulnerability is a Server-Side Request Forgery (SSRF) flaw in Red Hat Quay's build API that allows authenticated users to supply a malicious archive_url parameter. When a user with FEATURE_BUILD_SUPPORT enabled and repository write access provides a crafted URL, the Quay builder processes the request and makes outbound connections to attacker-specified internal network addresses. The attacker can bypass network-based access controls and access internal services, metadata endpoints, or services running on localhost. Exploitation requires prior authentication and repository write permissions, but no user interaction from other parties is required. Red Hat rates this as moderate severity (CVSS 4.2); the mitigation is to disable FEATURE_BUILD_SUPPORT if not needed.
