Answer in brief
CVE-2026-10517 records a Medium severity (CVSS 5.8) vulnerability in Claircore: Unauthenticated attackers can submit manifests with URIs pointing to internal services or cloud metadata endpoints. The current sources do not mark it as known exploited. The current feed maps github.com/quay/claircore (go), github.com/quay/claircore (go). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A flaw was found in Clair. The fetcher component makes outbound HTTP requests to attacker-supplied URIs from manifest layer descriptors without IP or scheme filtering. When PSK authentication is not configured (opt-in, not enforced by default), an unauthenticated attacker can submit a manifest with a URI pointing to internal services or cloud metadata endpoints. The SSRF is reflective for non-200 responses, leaking up to 256 bytes of error body content via CheckResponse error messages. Operator-managed Red Hat Quay deployments auto-configure PSK and are not exposed to the unauthenticated attack vector.
