AI-suggested
Upgrade MaxKB to version 2.9.0 or later, where this authentication bypass vulnerability is fixed. Until upgraded, restrict access to the webhook endpoint to trusted networks or implement external access controls to prevent unauthorized trigger invocation.
Description
MaxKB is an open-source AI assistant for enterprise. Prior to 2.9.0, MaxKB's webhook trigger endpoint (/api/trigger/v1/webhook/{trigger_id}) is accessible without authentication. The WebhookAuth class unconditionally returns (None, {}), which Django REST Framework interprets as successful authentication. Combined with optional per-trigger token verification and no backend enforcement of token requirements, any unauthenticated attacker who knows a valid trigger ID can invoke webhook triggers to execute their bound tasks. This vulnerability is fixed in 2.9.0.
