Server-side Request Forgery (SSRF)

Overview vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the P2pNcclConnector KV cache transfer connector, which exposes KV cache contents to network-accessible peers...

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

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...

vLLM server request forgery vulnerability

Versions prior to vLLM 0.24.0, specifically version 0.9.2, contain a server-side request forgery vulnerability. This vulnerability arises from embedding a decoding address within the X-Request-Id header, enabling server-side request forgery. Attackers can pre-populate the P2pNcclConnector with...
