{"id":"GHSA-698x-9w2p-7vvp","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.","aliases":["CVE-2026-10517","GO-2026-5939"],"modified":"2026-09-10T03:50:48.475919020Z","published":"2026-06-01T09:31:12Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-07-07T23:47:00Z","nvd_published_at":"2026-06-01T09:16:16Z","cwe_ids":["CWE-918"],"severity":"MODERATE"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-10517"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-10517"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2486779"},{"type":"PACKAGE","url":"https://github.com/quay/claircore"}],"affected":[{"package":{"name":"github.com/quay/claircore","ecosystem":"Go","purl":"pkg:golang/github.com/quay/claircore"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"1.5.52"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-698x-9w2p-7vvp/GHSA-698x-9w2p-7vvp.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N"}]}
