A server-side request forgery (SSRF) vulnerability has been identified in MaxKB, an open-source AI assistant for enterprise, in versions prior to 2.9.1. The issue arises in the workflow template import feature, where authenticated users can submit arbitrary URLs through the 'work_flow_template.downloadUrl' field. These URLs are fetched server-side without any validation, allowing access to internal IP addresses and cloud metadata endpoints. The vulnerability exists due to the absence of URL validation and internal IP filtering, particularly for private IP ranges and cloud metadata.
Users are advised to update to MaxKB version 2.9.1 or later, where this vulnerability has been fixed.
