{"id":"CVE-2026-10517","aliases":["GO-2026-5939"],"url":"https://o3.security/vulnerability/CVE-2026-10517","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.","published":"2026-06-01T09:31:12Z","modified":"2026-07-21T19:19:01.822786401Z","cvss":{"score":5.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N"},"epss":{"score":0.00292,"percentile":0.21421,"asOf":"2026-07-27"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/quay/claircore","fixedVersion":null}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-21T19:19:01.822786401Z"}}
