local-deep-research has an SSRF bypass in `safe_get`
GitHub lists this reviewed advisory for local-deep-research. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

### Summary The URL checking logic in local-deep-research has a logical flaw that could be bypassed by attackers, leading to SSRF attacks. ### Details The current project uses `validate_url` to validate the input URL. The main logic is to perform security checks on the host portion of the URL extracted by urlparse to prevent SSRF attacks. However, there are indeed differences in parsing between urlparse and the library that actually sends the request. For example, in `safe_get`, `validate_url` is first used to perform an SSRF check, and then `requests.get` is used to send the actual request. The core issue: urlparse() and requests disagree on which host a URL like `http://127.0.0.1:6666\@1.1.1.1` points to: - urlparse() treats \ as a regular character and @ as the userinfo-host delimiter, so it extracts hostname as `1.1.1.1` (public) - requests treats \ as a path character, connect
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. GitHub Advisory 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.
