CVE-2025-6242
Description
A Server-Side Request Forgery (SSRF) vulnerability exists in the MediaConnector class within the vLLM project's multimodal feature set. The load_from_url and load_from_url_async methods fetch and process media from user-provided URLs without adequate restrictions on the target hosts. This allows an attacker to coerce the vLLM server into making arbitrary requests to internal network resources.
Statement
This vulnerability has been rated as having the severity of Important by the Red Hat Product Security team as a successful exploitation by an attacker may lead to confidential data being leaked or a denial of service. Additionally the fact a unprivileged user can trigger this vulnerability through the network also contributes for the severity.
This vulnerability has its risk amplified on orchestrated environments as pods running the vLLM may eventually communicate with each other through internal cluster routing, including services that should not have been exposed to external networks. An attacker may leverage this flaw to interact with internal services, perform network reconnaissance or trigger a denial of service by leading other internal services to fail.
Mitigation
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
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).
