What is CVE-2026-33626?

The LMDeploy toolkit, which handles the compression and deployment of large language models, is affected by a Server-Side Request Forgery (SSRF) vulnerability in its vision-language module. Specifically, the load_image() function within the lmdeploy/vl/utils.py file fetches arbitrary URLs without appropriate validation of internal or private IP addresses. This oversight may allow attackers to exploit this vulnerability to access sensitive resources, including cloud metadata services and internal networks. Users are advised to upgrade to version 0.12.3, where this issue has been resolved.

Affected Version(s)
