{"cve":"CVE-2025-68151","nvd":{"published":"2026-01-08T16:15:59.847","modified":"2026-10-14T16:10:00.250","status":"Analyzed","description":"CoreDNS is a DNS server that chains plugins. Prior to version 1.14.0, multiple CoreDNS server implementations (gRPC, HTTPS, and HTTP/3) lack critical resource-limiting controls. An unauthenticated remote attacker can exhaust memory and degrade or crash the server by opening many concurrent connections, streams, or sending oversized request bodies. The issue is similar in nature to CVE-2025-47950 (QUIC DoS) but affects additional server types that do not enforce connection limits, stream limits, or message size constraints. Version 1.14.0 contains a patch.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U","score":6.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/coredns/coredns/commit/0d8cbb1a6bcb6bc9c1a489865278b8725fa20812","https://github.com/coredns/coredns/pull/7490","https://github.com/coredns/coredns/security/advisories/GHSA-527x-5wrf-22m2"],"products":["coredns.io:coredns"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-68151","score":0.00494,"percentile":0.42112,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-527x-5wrf-22m2","url":"https://osv.dev/vulnerability/GHSA-527x-5wrf-22m2","summary":"CoreDNS gRPC/HTTPS/HTTP3 servers lack resource limits, enabling DoS via unbounded connections and oversized messages","modified":"2026-09-10T03:50:32.671916252Z","packages":[{"ecosystem":"Go","name":"github.com/coredns/coredns","purl":"pkg:golang/github.com/coredns/coredns","ranges":["<1.14.0"],"fixed":["1.14.0"]}]},{"id":"GO-2026-4289","url":"https://osv.dev/vulnerability/GO-2026-4289","summary":"CoreDNS gRPC/HTTPS/HTTP3 servers lack resource limits, enabling DoS via unbounded connections and oversized messages in github.com/coredns/coredns","modified":"2026-02-04T02:40:54.680007Z","packages":[{"ecosystem":"Go","name":"github.com/coredns/coredns","purl":"pkg:golang/github.com/coredns/coredns","ranges":["<1.14.0"],"fixed":["1.14.0"]}]}],"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).
