source listed<= 0.12.2
## Summary 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. ## Affected Versions - **Tested on:** main branch (2026-02-04) - **Affected:** All versions prior to 0.12.3 ## Vulnerable Code **File:** `lmdeploy/vl/utils.py` (lines 64-67) ```python 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) ## Root Cause 1. No validation of URLs before fetching 2. No blocklist for internal IPs (127.0.0.1, 169.254.x.x, 10.x.x.x, 192.168.x.x) 3. Server binds to `0.0.0.0` by default (api_server.py line 1393) 4. API keys disabled by default ## Attack Scenario 1. LMDeploy server deployed with vision-language model 2. Attacker sends request to `/v1/chat/completions
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. NIST National Vulnerability Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
- NVD lastModified does not establish freshness of every associated CPE record.
05 / Provenance
Sources you can inspect
