Starting in version 1.2.0 and prior to version 1.12.4, the CoreDNS etcd plugin contains a TTL confusion vulnerability where lease IDs are incorrectly used as TTL values, enabling DNS cache pinning attacks. This effectively creates a DoS condition for DNS resolution of affected services. The `TTL()` function in `plugin/etcd/etcd.go` incorrectly casts etcd lease IDs (64-bit integers) to uint32 and uses them as TTL values. Large lease IDs become very large TTLs when cast to uint32. This enables cache pinning attacks. Version 1.12.4 contains a fix for the issue.","state":0,"publishedAt":"2025-09-09T20:15:48.057+00:00","modifiedAt":"2026-10-19T17:10:00.173+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","score":7.1,"severity":"HIGH"}],"references":["https://github.com/coredns/coredns/commit/e1768a5d272e9da649dfb8588595e5c6e4e640bf","https://github.com/coredns/coredns/security/advisories/GHSA-93mf-426m-g6x9"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-58063","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-681"],"productCriteria":[],"sourceDates":{"published":"2025-09-09T20:15:48.057","lastModified":"2026-10-19T17:10:00.173"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
