Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 14 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.858.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. 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. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-03T20:26:43.833Z - **Finished:** 2026-11-03T20:28:06.404Z - **Download time:** 6128 ms - **Static scan time:** 5871 ms - **AI review time:** 70571 ms - **Total time:** 82571 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Undisclosed runtime feature telemetry records flow editor panel placement. - **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. - **Evidence paths:** package/components/FlowBuilder.svelte, package/components/flows/flowEditorTelemetry.js, package/utils/featureUsage.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T20:28:06.404Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The component aggregates placement counters and sends them with the session cookie to the configured Windmill API. - **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. - **Network endpoints:** ${OpenAPI.BASE}/w/{workspace}/workspaces/log\_feature\_usage ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **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. ## Affected versions and remediation This report applies to @windmill-labs/components@1.858.1. - Review the evidence and your use of @windmill-labs/components@1.858.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.

High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** package/assets/app.css - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```css stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 207 ``` ### 14. Critical: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** package/components/FlowBuilder.svelte - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```text matchType = previous_version_dangerous_delta matchedPackage = @windmill-labs/components@1.830.0 matchedIdentity = npm:[redacted]:1.830.0 similarity = 0.867 summary = stored previous version shares package body but lacks this dangerous source file ``` ## Dependencies and install lifecycle -
