CVE-2025-64511Network attack vector

Internal service access via sandboxed Python code

Published Nov 13, 2025 · Updated Nov 13, 2025

SSRF in MaxKB before 2.3.1 allows remote authenticated users to access internal network services through tool-module Python code. The tool module executes user-supplied Python in a sandbox that does not prevent connections to internal services, including databases. A low-privileged account and tool-module access are required; the bounded consequence is server-side access to services reachable from the sandbox.
