Executive Summary

This vulnerability exists in MaxKB, an open-source AI assistant for enterprise, in versions prior to 2.9.1. It is a Server-Side Request Forgery (SSRF) issue that occurs via the work_flow_template import feature. Authenticated users can provide arbitrary URLs in the work_flow_template.downloadUrl parameter, which the server fetches without validating the URL or filtering internal IP addresses.

Because the server does not check or restrict these URLs, an attacker could potentially make the server send requests to unintended locations, including internal network resources.

Impact Analysis

This SSRF vulnerability can allow an authenticated attacker to make the server perform unauthorized requests to internal or external systems. This could lead to information disclosure, unauthorized access to internal services, or other malicious activities depending on the internal network configuration and the resources accessible by the server.

Mitigation Strategies

To mitigate this vulnerability, upgrade MaxKB to version 2.9.1 or later, where the SSRF issue via work_flow_template Import has been fixed.

Additionally, restrict authenticated users from supplying arbitrary URLs in work_flow_template.downloadUrl until the upgrade is applied.
