{"id":"CVE-2026-110719","summary":"Portkey AI Gateway 1.14.0 through 1.15.2 SSRF via x-portkey-custom-host Header","details":"Portkey AI Gateway 1.14.0 through 1.15.2 contains a server-side request forgery vulnerability that allows unauthenticated attackers to reach loopback and Docker host services because isValidCustomHost trusts localhost-style hosts when TRUSTED_CUSTOM_HOSTS is unset. Attackers can send /v1 requests with a crafted x-portkey-custom-host header, such as via the ollama provider, to make the gateway call internal services and return their responses.","modified":"2026-10-16T02:47:39.874735851Z","published":"2026-10-14T15:01:32.488Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110719.json","cna_assigner":"VulnCheck"},"references":[{"type":"WEB","url":"https://www.npmjs.com"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110719.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110719"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/portkey-ai-gateway-1.14.0-through-1.15.2-ssrf-via-x-portkey-custom-host-header"},{"type":"PACKAGE","url":"https://github.com/Portkey-AI/gateway"},{"type":"ARTICLE","url":"https://github.com/Portkey-AI/gateway/blob/ca7712947ec8c0887803990b746740d36011c697/src/middlewares/requestValidator/index.ts#L289"},{"type":"EVIDENCE","url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/BJypv-aiMg"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/portkey-ai/gateway","events":[{"introduced":"da1a1d04fe3578bdeafbbcbe035f278030f02cfb"},{"fixed":"ca7712947ec8c0887803990b746740d36011c697"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"1.14.0"},{"last_affected":"1.15.2"},{"fixed":"1.15.2"}]}}],"versions":["v1.15.1","v1.15.0","v1.14.3","v1.14.2","v1.14.0","v1.14.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110719.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
