CVE-2026-64870Public exploitNetwork attack vector

Authenticated internal requests via incomplete URL validation

Published Jul 30, 2026 · Updated Jul 30, 2026

Server-side request forgery in FIT2CLOUD MaxKB 2.0.0 through 2.10.4-lts allows remote authenticated users to reach internal URLs. UpdateStoreTool.update_tool uses only a string-prefix check for download_url, performs no validation for download_callback_url, and lets requests.get follow redirects. A low-privilege workspace account is sufficient to probe internal HTTP services or contact loopback, link-local, and metadata addresses; response-body disclosure is not established.
