{"cve":"CVE-2025-64513","nvd":{"published":"2025-11-10T22:15:40.270","modified":"2026-06-17T09:54:29.670","status":"Deferred","description":"Milvus is an open-source vector database built for generative AI applications. An unauthenticated attacker can exploit a vulnerability in versions prior to 2.4.24, 2.5.21, and 2.6.5 to bypass all authentication mechanisms in the Milvus Proxy component, gaining full administrative access to the Milvus cluster. This grants the attacker the ability to read, modify, or delete data, and to perform privileged administrative operations such as database or collection management. This issue has been fixed in Milvus 2.4.24, 2.5.21, and 2.6.5. If immediate upgrade is not possible, a temporary mitigation can be applied by removing the sourceID header from all incoming requests at the gateway, API gateway, or load balancer level before they reach the Milvus Proxy. This prevents attackers from exploiting the authentication bypass behavior.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":null,"cwes":["CWE-287"],"references":["https://github.com/milvus-io/milvus/pull/45379","https://github.com/milvus-io/milvus/pull/45383","https://github.com/milvus-io/milvus/pull/45391","https://github.com/milvus-io/milvus/security/advisories/GHSA-mhjq-8c7m-3f7p"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:14:53.307938015+00:00"},"epss":{"cve":"CVE-2025-64513","score":0.00869,"percentile":0.58775,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mhjq-8c7m-3f7p","url":"https://osv.dev/vulnerability/GHSA-mhjq-8c7m-3f7p","summary":"Milvus Proxy has a Critical Authentication Bypass Vulnerability","modified":"2026-02-20T09:26:04.105984Z","packages":[{"ecosystem":"Go","name":"github.com/milvus-io/milvus","purl":"pkg:golang/github.com/milvus-io/milvus","ranges":[">=0.10.4 <2.4.24"],"fixed":["2.4.24"]},{"ecosystem":"Go","name":"github.com/milvus-io/milvus","purl":"pkg:golang/github.com/milvus-io/milvus","ranges":[">=2.5.0 <2.5.21"],"fixed":["2.5.21"]},{"ecosystem":"Go","name":"github.com/milvus-io/milvus","purl":"pkg:golang/github.com/milvus-io/milvus","ranges":[">=2.6.0 <2.6.5"],"fixed":["2.6.5"]},{"ecosystem":"Go","name":"github.com/milvus-io/milvus","purl":"pkg:golang/github.com/milvus-io/milvus","ranges":["<0.10.3-0.20251107071934-6102f001a971"],"fixed":["0.10.3-0.20251107071934-6102f001a971"]}]},{"id":"GO-2025-4114","url":"https://osv.dev/vulnerability/GO-2025-4114","summary":"Milvus Proxy has a Critical Authentication Bypass Vulnerability in github.com/milvus-io/milvus","modified":"2026-02-20T09:26:04.105984Z","packages":[{"ecosystem":"Go","name":"github.com/milvus-io/milvus","purl":"pkg:golang/github.com/milvus-io/milvus","ranges":["<0.10.3-0.20251107071934-6102f001a971",">=0.10.4"],"fixed":["0.10.3-0.20251107071934-6102f001a971"]}]}],"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).
