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.","cvssScore":7.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Portkey-AI/gateway","tags":[]},{"url":"https://github.com/Portkey-AI/gateway/blob/ca7712947ec8c0887803990b746740d36011c697/src/middlewares/requestValidator/index.ts#L289","tags":[]},{"url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/BJypv-aiMg","tags":[]},{"url":"https://www.vulncheck.com/advisories/portkey-ai-gateway-1.14.0-through-1.15.2-ssrf-via-x-portkey-custom-host-header","tags":[]}],"exploitRefs":[{"url":"https://github.com/Portkey-AI/gateway","tags":[]},{"url":"https://github.com/Portkey-AI/gateway/blob/ca7712947ec8c0887803990b746740d36011c697/src/middlewares/requestValidator/index.ts#L289","tags":[]}],"hasPoc":true,"ai":null}
