Portkey.ai Gateway: Server-Side Request Forgery (SSRF) in Custom Host_CVE-2025-66405

{
    "lastseen": "",
    "description": "Portkey.ai Gateway is a blazing fast AI Gateway with integrated guardrails. Prior to 1.14.0, the gateway determined the destination baseURL by prioritizing the value in the x-portkey-custom-host request header. The proxy route then appends the client-specified path to perform an external fetch. This can be maliciously used by users for SSRF attacks. This vulnerability is fixed in 1.14.0.",
