Description

MaxKB is an open-source AI assistant for enterprise. In version 2.10.3-lts and earlier, the knowledge web-document import and synchronization crawler passes an authenticated workspace user's URL to Fork.fork, which calls requests.get with verify=False and without restricting schemes, loopback, link-local, private, or reserved addresses. The response body is converted into imported document content, allowing a low-privileged user to read cloud metadata or internal HTTP services through the MaxKB server. No fixed version is available as of this review.
