When receiving a request from a source IP address that was not listed in proxy_protocol_authorized_addrs, the Vault API server would shut down and no longer respond to any HTTP requests, potentially resulting in denial of service.\n\nWhile this bug also affected versions of Vault up to 1.17.1 and 1.16.5, a separate regression in those release series did not allow Vault operators to configure the deny_unauthorized option, thus not allowing the conditions for the denial of service to occur.\n\nFixed in Vault and Vault Enterprise 1.17.2, 1.16.6, and 1.15.12.","cvss_v4":null,"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-703"],"references":["https://discuss.hashicorp.com/t/hcsec-2024-14-vault-vulnerable-to-denial-of-service-when-setting-a-proxy-protocol-behavior/68518","https://discuss.hashicorp.com/t/hcsec-2024-14-vault-vulnerable-to-denial-of-service-when-setting-a-proxy-protocol-behavior/68518"],"products":["hashicorp:vault"],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2024-6468","score":0.00491,"percentile":0.42214,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2qmw-pvf7-4mw6","url":"https://osv.dev/vulnerability/GHSA-2qmw-pvf7-4mw6","summary":"Hashicorp Vault vulnerable to Improper Check or Handling of Exceptional Conditions ","modified":"2026-09-10T03:50:16.153292263Z","packages":[{"ecosystem":"Go","name":"github.com/hashicorp/vault","purl":"pkg:golang/github.com/hashicorp/vault","ranges":[">=1.10.0 <1.15.12"],"fixed":["1.15.12"]},{"ecosystem":"Go","name":"github.com/hashicorp/vault","purl":"pkg:golang/github.com/hashicorp/vault","ranges":[">=1.16.0-rc1 <1.16.3"],"fixed":["1.16.3"]},{"ecosystem":"Go","name":"github.com/hashicorp/vault","purl":"pkg:golang/github.com/hashicorp/vault","ranges":[">=1.17.0-rc1 <1.17.2"],"fixed":["1.17.2"]}]},{"id":"GO-2024-2982","url":"https://osv.dev/vulnerability/GO-2024-2982","summary":"Hashicorp Vault vulnerable to Improper Check or Handling of Exceptional Conditions in github.com/hashicorp/vault","modified":"2026-02-04T02:25:45.877648Z","packages":[{"ecosystem":"Go","name":"github.com/hashicorp/vault","purl":"pkg:golang/github.com/hashicorp/vault","ranges":[">=1.10.0 <1.16.3",">=1.17.0-rc1 <1.17.2"],"fixed":["1.16.3","1.17.2"]}]}],"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).
