CWE-918
AllowedServer-Side Request Forgery (SSRF)
Abstraction: Base · Status: Incomplete
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
4719 vulnerabilities reference this CWE, most recent first.
GHSA-HHH5-2CVX-VMFP
Vulnerability from github – Published: 2025-12-02 01:08 – Updated: 2025-12-02 01:08Summary
The gateway determines 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 (CWE-918) attack
Impact
This vulnerability can be exploited to force the server to make requests to arbitrary hosts on the internal network. This could allow an attacker to exfiltrate sensitive data, for instance, by accessing the AWS metadata service.
Patches
The issue is patched in 1.14.0 (https://github.com/Portkey-AI/gateway/pull/1372)
The vulnerability resides within the gateway's request processing function which handles the x-portkey-custom-host header. This parameter was passed directly or with insufficient validation/sanitization to an internal HTTP request function.
The fix (v1.14.0) implements a robust allow-list policy:
-
All custom host inputs are now strictly validated to ensure the resulting URI points only to trusted, expected external services.
-
The implementation now explicitly blocks requests to non-routable IP addresses, loopback addresses, private networks and standard metadata endpoints.
Credit
This vulnerability was discovered and reported responsibly by @im-soohyun. We thank them for their adherence to coordinated vulnerability disclosure principles.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
