What is CVE-2026-110719?

The Portkey AI Gateway versions 1.14.0 through 1.15.2 are susceptible to a server-side request forgery (SSRF) vulnerability. This issue arises from improper validation of localhost-style hosts when the TRUSTED_CUSTOM_HOSTS setting is absent. Unauthenticated attackers can exploit this vulnerability by sending specially crafted requests with an x-portkey-custom-host header. As a result, attackers may be able to access internal services on loopback and Docker host interfaces, potentially exposing sensitive information and enabling further attacks.

Affected Version(s)

gateway 1.14.0 <= 1.15.2

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
