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...
