Flowise advisory alleges a custom-function sandbox escape through Mammoth

An unreviewed advisory for Flowise through 3.1.4 reports a route from attacker-controlled LocalFileStore content to built-in Mammoth dependency execution when ALLOW_BUILTIN_DEP is enabled.

Scope

Unreviewed external advisory; setting-specific proof, affected versions and official remediation status need verification, with no known production exploitation.

Basis and provenance

The advisory reports a sandbox escape from Flowise custom-function execution through a dependency loading path. Treat the effect as a reported reproduction requiring the affected configuration, not proof of universal remote code execution. Impact remains unrated because the evidence does not supply a calibrated scale for this Case.

Implications

Assess the reported tool or model action separately from the side effect actually observed.

Controls and mitigations

  • Disable unnecessary built-in module access in custom tools, isolate the host worker process and validate the vendor patch status before relying on a version-only fix.

Unknowns and contradictions

  • Unreviewed external advisory; setting-specific proof, affected versions and official remediation status need verification, with no known production exploitation.
