{"cve":"CVE-2025-58063","nvd":{"published":"2025-09-09T20:15:48.057","modified":"2026-10-19T17:10:00.173","status":"Deferred","description":"CoreDNS is a DNS server that chains plugins. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","score":7.1},"cwes":["CWE-681"],"references":["https://github.com/coredns/coredns/commit/e1768a5d272e9da649dfb8588595e5c6e4e640bf","https://github.com/coredns/coredns/security/advisories/GHSA-93mf-426m-g6x9","https://github.com/coredns/coredns/security/advisories/GHSA-93mf-426m-g6x9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:08:41.295252406+00:00"},"epss":{"cve":"CVE-2025-58063","score":0.00506,"percentile":0.42941,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-93mf-426m-g6x9","url":"https://osv.dev/vulnerability/GHSA-93mf-426m-g6x9","summary":"CoreDNS: DNS Cache Pinning via etcd Lease ID Confusion","modified":"2026-09-10T03:50:28.063943124Z","packages":[{"ecosystem":"Go","name":"github.com/coredns/coredns","purl":"pkg:golang/github.com/coredns/coredns","ranges":[">=1.2.0 <1.12.4"],"fixed":["1.12.4"]}]},{"id":"GO-2025-3942","url":"https://osv.dev/vulnerability/GO-2025-3942","summary":"CoreDNS: DNS Cache Pinning via etcd Lease ID Confusion in github.com/coredns/coredns","modified":"2026-02-04T02:26:40.371617Z","packages":[{"ecosystem":"Go","name":"github.com/coredns/coredns","purl":"pkg:golang/github.com/coredns/coredns","ranges":[">=1.2.0 <1.12.4"],"fixed":["1.12.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
