| Description | MaxKB is an open-source AI assistant for enterprise. In versions 2.0.0 through 2.10.4-lts, UpdateStoreTool.update_tool passes caller-supplied download_url and download_callback_url values to requests.get without equivalent trusted-host and redirect validation, allowing an authenticated workspace user to make the server request internal, loopback, link-local, or cloud metadata URLs. A fix is present on the v2 branch but has not yet been included in a published release. |
