{"schema":"threatline.record/2","record":{"id":"CVE-2026-92543","aliases":["GHSA-7cfq-22r6-qp73"],"summary":"Docker Engine insecure-registry fallback via malicious DNS responses","details":"Docker Engine classifies a registry hostname as insecure using an any-match DNS check. loadInsecureRegistries() injects 127.0.0.0/8 and ::1/128 as insecure CIDRs by default. isCIDRMatch resolves all of the hostname's addresses and returns true if a single address is in the insecure CIDR list. Because the transport re-dials the hostname rather than the CIDR-matching address, a DNS answer set of one loopback IP plus a non-loopback attacker IP disables certificate verification and enables HTTP fallback for the registry connection.","categories":["Containers & cloud"],"product":"Docker Engine","vendor":"Docker","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92543","source_modified_at":"2026-10-07T20:31:28.770Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Docker Engine","vendor":"Docker","versions":[{"version":"0","status":"affected","lessThan":"29.8.2","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92543","source_modified_at":"2026-10-07T20:31:28.770Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Moby","vendor":"Moby","versions":[{"version":"0","status":"affected","lessThan":"v2.0.0-beta.25","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/moby/moby/security/advisories/GHSA-7cfq-22r6-qp73","source_modified_at":"2026-10-01T21:19:06Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"go","name":"github.com/moby/moby/v2"},"range":"< v2.0.0-beta.25"},{"source":"GitHub Advisory Database","source_url":"https://github.com/moby/moby/security/advisories/GHSA-7cfq-22r6-qp73","source_modified_at":"2026-10-01T21:19:06Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"","name":"Docker Engine"},"range":"< 29.8.2"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92543","source_modified_at":"2026-10-07T20:31:28.770Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Docker Engine","ecosystem":null},"version":"29.8.2","basis":"first unaffected version stated in the CVE record"},{"source":"GitHub Advisory Database","source_url":"https://github.com/moby/moby/security/advisories/GHSA-7cfq-22r6-qp73","source_modified_at":"2026-10-01T21:19:06Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"","name":"Docker Engine"},"version":"29.8.2"}],"cvss":7.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00087,"percentile":0.0034,"score_date":"2026-10-23"},"published_at":"2026-10-07T16:44:21.237Z","modified_at":"2026-10-07T20:31:28.770Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92543","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-07T20:31:28.770Z"},{"source":"GitHub Advisory Database","url":"https://github.com/moby/moby/security/advisories/GHSA-7cfq-22r6-qp73","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-01T21:19:06Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92543","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/moby/moby/security/advisories/GHSA-7cfq-22r6-qp73","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-07T20:31:15.802430Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-07T20:31:28.770Z","content_hash":"7e60c2c8f189848072b36b671bff90b96d75a21ce6cef46fd36542140521ef70"}}
