CVE-2026-41268: Flowise unauthenticated remote command execution via parameter override bypass

Summary

CVE-2026-41268 affects Flowise, a drag-and-drop interface for building customized LLM flows, prior to 3.1.0. A parameter override bypass using the FILE-STORAGE:: keyword, combined with NODE_OPTIONS environment variable injection, lets an unauthenticated attacker run arbitrary system commands with root privileges inside the containerized Flowise instance. Exploitation needs only a single HTTP request and no prior knowledge of the instance.

Mitigation

Fixed in 3.1.0.
