Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in MaxKB versions 2.0.0 through 2.10.4-lts within the `UpdateStoreTool.update_tool` function. The application fails to validate the `download_url` and `download_callback_url` parameters before passing them to the `requests.get` method. An authenticated workspace user can provide malicious URLs pointing to loopback addresses, internal network services, or cloud metadata endpoints (e.g., 169.254.169.254). While the application enforces host-locking in other components, this specific path lacks equivalent trusted-host or redirect validation. A fix involving centralized URL validation has been committed to the v2 branch but may not be in all published releases.
