CVE-2026-25960
Description
A flaw was found in vLLM, an inference and serving engine for large language models (LLMs). A remote attacker can exploit this Server-Side Request Forgery (SSRF) bypass vulnerability in the load_from_url_async method. The flaw occurs because the URL validation and the actual HTTP request handling use different parsing libraries, leading to inconsistencies. This allows an attacker to bypass existing SSRF protections, potentially leading to the disclosure of sensitive information from internal network resources.
Statement
This is an IMPORTANT vulnerability. The vLLM component, as used in Red Hat AI Inference Server and Red Hat OpenShift AI, is affected by a Server-Side Request Forgery (SSRF) protection bypass. This flaw allows an attacker to circumvent existing SSRF safeguards due to inconsistent URL parsing between the validation layer and the underlying HTTP client when the load_from_url_async method is utilized.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
