AI Security Review
scanned 1d ago · by lpm-firewall-aiThe flagged credential references do not show automatic credential collection, and the postinstall hook is guarded by a script-existence check. However, FlowBuilder enables runtime feature telemetry by default, and the reviewed source shows no user-facing disclosure or opt-out, so this warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
FlowBuilder is instantiated outside a session preview pane and placement events occur.
Impact
The backend receives workspace-associated feature usage without an evident user-facing disclosure or opt-out in the reviewed code.
Mechanism
The component aggregates placement counters and sends them with the session cookie to the configured Windmill API.
AI rationale
The flagged credential references do not show automatic credential collection, and the postinstall hook is guarded by a script-existence check. However, FlowBuilder enables runtime feature telemetry by default, and the reviewed source shows no user-facing disclosure or opt-out, so this warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Flow editor telemetry emits only aggregated placement counters with a small fixed vocabulary and says it excludes paths, expressions, and step IDs.
- The telemetry helper POSTs events with the session cookie to the configured Windmill API base at `/w/{workspace}/workspaces/log_feature_usage`.
- FlowBuilder enables this telemetry by default outside session preview panes; no user-facing consent or opt-out appears in the reviewed flow.
- The postinstall hook checks whether `scripts/untar_ui_builder.js` exists before running it; that script was absent from the inspected snapshot.
Evidence against
- The event data is limited to anonymous feature, kind, and placement keys; no flow content or credentials are included in the event payload.
- Network reporting goes to the configured Windmill backend, and the other flagged credential references are UI labels or configuration fields rather than automatic credential collection.
