It is possible but very inconvenient to check the validation status of individual records. These methods should instead return an error when DNSSEC validation determines a response is bogus.","severity":"high","score":7.5,"published":"2026-09-03T12:00:00.000Z","modified":"2026-11-12T14:40:54.257Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"crates.io","name":"hickory-resolver","sources":[{"name":"OSV · GHSA-5j98-2g5x-46v6","url":"https://osv.dev/vulnerability/GHSA-5j98-2g5x-46v6"}],"ranges":[{"events":[{"introduced":"0"},{"fixed":"0.26.2"}],"type":"SEMVER"}],"versions":[],"fixed":["0.26.2"]},{"ecosystem":"crates.io","name":"hickory-resolver","sources":[{"name":"OSV · RUSTSEC-2026-0514","url":"https://osv.dev/vulnerability/RUSTSEC-2026-0514"}],"ranges":[{"events":[{"introduced":"0.0.0-0"},{"fixed":"0.26.2"}],"type":"SEMVER"}],"versions":[],"fixed":["0.26.2"]}],"sourceAffected":[],"references":["https://github.com/hickory-dns/hickory-dns/security/advisories/GHSA-5j98-2g5x-46v6","https://github.com/hickory-dns/hickory-dns/pull/3871","https://github.com/hickory-dns/hickory-dns/commit/92f93c0b889f6a292bc943304d88c4c6561fe1b9","https://github.com/hickory-dns/hickory-dns","https://github.com/hickory-dns/hickory-dns/releases/tag/v0.26.2","https://crates.io/crates/hickory-resolver","https://rustsec.org/advisories/RUSTSEC-2026-0514.html","https://github.com/hickory-dns/hickory-dns/commit/30720f4fb22e5556ecbf26d2c8274ea4a9fdd238"],"sources":[{"name":"OSV","id":"GHSA-5j98-2g5x-46v6","modified":"2026-11-12T14:40:54.257337988Z","url":"https://osv.dev/vulnerability/GHSA-5j98-2g5x-46v6"},{"name":"OSV","id":"RUSTSEC-2026-0514","modified":"2026-11-12T14:30:06.143103321Z","url":"https://osv.dev/vulnerability/RUSTSEC-2026-0514"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5}],"products":[],"remediation":[],"observedAt":"2026-11-12T21:53:02.572Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T04:10:32.324Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-13T01:55:34.682Z","attemptedAt":"2026-11-13T01:55:34.682Z"},{"source":"GHSA","status":"available","checkedAt":"2026-11-13T01:55:33.379Z","attemptedAt":"2026-11-13T01:55:33.379Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-13T01:55:32.512Z","attemptedAt":"2026-11-13T01:55:32.512Z"},{"source":"EPSS","status":"available","checkedAt":"2026-11-13T01:55:33.662Z","attemptedAt":"2026-11-13T01:55:33.662Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-82939","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-82939","modified":"Sep 21, 2026, 8:51:40 PM","score":8.7,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","checkedAt":"2026-11-13T01:55:32.512Z"},{"source":"GitHub Advisory Database","id":"GHSA-884w-h442-q7ph","url":"https://github.com/advisories/GHSA-884w-h442-q7ph","modified":"2026-09-18T15:32:31Z","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","checkedAt":"2026-11-13T01:55:33.379Z"},{"source":"FIRST EPSS","id":"CVE-2026-93657","url":"https://www.first.org/epss/","probability":0.00231,"percentile":0.14051,"date":"2026-11-12","checkedAt":"2026-11-13T01:55:33.662Z"},{"source":"NVD","id":"CVE-2026-93657","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93657","modified":"2026-09-22T20:53:07.383","score":8.7,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","checkedAt":"2026-11-13T01:55:34.682Z"},{"source":"NVD","id":"CVE-2026-93657","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93657","modified":"2026-09-22T20:53:07.383","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","checkedAt":"2026-11-13T01:55:34.682Z"}],"aiSummary":null}
