CVE-2026-10517 (GCVE-0-2026-10517)

Vulnerability from cvelistv5 – Published: 2026-06-01 07:56 – Updated: 2026-07-27 08:35

Retracted following review by Red Hat Product Security and confirmation from the upstream Clair/Claircore maintainer. This CVE misattributes the described behavior to github.com/quay/claircore: the authentication mechanism in question (optional PSK, HTTP endpoint /indexer/api/v1/index_report) is implemented entirely in github.com/quay/clair; no PSK-related code exists anywhere in claircore's codebase or git history. The unauthenticated indexer API is Clair's documented, intentional design, authentication is an opt-in deployment choice, not a code defect. No fix commit was found in claircore between the version recorded as the affected boundary (1.5.52) and the following release (1.5.53); intervening commits are unrelated dependency and feature changes, so the "fixed in 1.5.52" status is inaccurate.

Vulnerability from github – Published: 2026-06-01 09:31 – Updated: 2026-07-07 23:47

Summary

Claircore: Unauthenticated attackers can submit manifests with URIs pointing to internal services or cloud metadata endpoints

Details

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.

Severity

5.8 (Medium)
