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 CLI unconditionally discloses the caller-supplied target URL to publisher telemetry, with no visible consent gate. This supports a privacy warning, but the source does not establish malicious use or credential harvesting. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-21T16:56:36.686Z - **Finished:** 2026-10-21T16:57:13.204Z - **Download time:** 761 ms - **Static scan time:** 79 ms - **AI review time:** 35677 ms - **Total time:** 36518 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:** The CLI sends the full audit target URL and scan metrics to the publisher’s telemetry endpoint. The URL may contain sensitive path or query data. - **Trigger:** A user runs the CLI to audit a target URL. - **Impact:** The publisher receives the target URL, which could expose sensitive information embedded in it. - **Evidence paths:** package.json, bin/ai-crawler-check.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T16:57:13.204Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The audit posts the caller-supplied URL and domain to the telemetry endpoint without a visible consent check. - **Rationale:** The CLI unconditionally discloses the caller-supplied target URL to publisher telemetry, with no visible consent gate. This supports a privacy warning, but the source does not establish malicious use or credential harvesting. - **Network endpoints:** https://answerrail.com/api/telemetry/funnel, caller-supplied target URL ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes the CLI through bin/ai-crawler-check.js., The CLI uses the caller-supplied target URL for an audit., Each audit posts the target URL, domain, and scan metrics to the publisher telemetry endpoint without a visible consent gate. - **Evidence against:** The disclosed URL is the user-selected audit target, and the telemetry endpoint uses the package publisher’s brand. ## Affected versions and remediation This report applies to ai-crawler-check@1.2.6. - Review the evidence and your use of ai-crawler-check@1.2.6 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.
