CVE-2026-116176

vLLM from 0.9.2 before 0.24.0 contains a server-side request forgery vulnerability that allows API callers to force outbound connections by embedding a decode address in the X-Request-Id header. Attackers can make a P2pNcclConnector prefill worker ZMQ-connect to an attacker host, leaking the NCCL...

CVE-2026-116176

A flaw was found in vLLM. This vulnerability allows a remote attacker to trigger a Server-Side Request Forgery SSRF by submitting an HTTP request containing a crafted X-Request-Id header. Because the application extracts network addresses from this header without validation, backend workers can b...

CVE-2026-116176

The vLLM library (versions 0.9.2 before 0.24.0) contains a Server-Side Request Forgery (SSRF) vulnerability in the P2pNcclConnector component. An attacker can force outbound connections by embedding a decoded address within the X-Request-Id header. This allows an attacker to make a prefill worker...
