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 12 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:** 4.109.0 - **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 package’s runtime error reporting is disclosed and can be disabled, but it forwards detailed error objects and request data, which may include identifying project context. This is a telemetry risk rather than evidence of credential theft or a malicious install action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-31T12:34:50.642Z - **Finished:** 2026-10-31T12:35:42.573Z - **Download time:** 1518 ms - **Static scan time:** 581 ms - **AI review time:** 49831 ms - **Total time:** 51931 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:** Default runtime error telemetry may send project-specific diagnostics to Datadog. - **Trigger:** The CLI starts with telemetry enabled; reports are sent when errors occur, including on a server error path. - **Impact:** Diagnostic payloads can expose project-specific request details or local context. The package announces telemetry and provides an opt-out. - **Evidence paths:** dist/cli/log.js, dist/server/rest-api.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T12:35:42.573Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The logger forwards error objects, messages, extra metadata, and in one handler request query data and a URL to a Datadog sender. - **Rationale:** The package’s runtime error reporting is disclosed and can be disabled, but it forwards detailed error objects and request data, which may include identifying project context. This is a telemetry risk rather than evidence of credential theft or a malicious install action. - **Network endpoints:** Datadog; the host is delegated to @knapsack/logger and is not specified in this package source. ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI logger enables Datadog reporting by default outside the monorepo and provides a telemetry opt-out., Error reports include the error message, Error object, and extra metadata., A server error handler reports request query data and the request URL to Datadog. - **Evidence against:** The CLI displays that telemetry is on and explains how to disable it., The package has no install lifecycle scripts; its npm scripts are build, clean, lint, and test. ## Affected versions and remediation This report applies to @knapsack/app@4.109.0. - Review the evidence and your use of @knapsack/app@4.109.0 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.
