4.3 MEDIUMpublic exploit available

Published 2026-09-21 · Updated 2026-09-21

AI risk analysis

Summary
The flaw allows a low-privileged user to read cloud metadata or internal HTTP services by importing documents through MaxKB's document import feature due to insecure requests.get calls with verify=False. This matters because it can lead to unauthorized data exposure.
Exploitability
Exploitation requires access to the authenticated workspace and knowledge of the URL format, making it moderately difficult but feasible for attackers in controlled environments.
Blast radius
If exploited, this could result in significant data breaches affecting internal services and cloud metadata visibility within the organization.
Prioritized remediation
Update MaxKB to a version that restricts schemes, disables loopback, link-local, private, or reserved address access, and ensures secure HTTPS requests.

NVD 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.
