LMDeploy - Server-Side Request Forgery

CVE-2026-33626
Verified

Description

LMDeploy is a toolkit for compressing, deploying, and serving large language models. Versions prior to 0.12.3 have a Server-Side Request Forgery (SSRF) vulnerability in the vision-language module. The load_image() function in lmdeploy/vl/utils.py fetches arbitrary URLs without validating internal or private IP addresses, allowing unauthenticated attackers to access cloud metadata services, internal networks, and sensitive resources via the image_url parameter in /v1/chat/completions requests.
