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. A transitive dependency documents and implements sampled runtime telemetry that reports the page hostname and site key to Prosopo for self-hosted widgets. Because the package README says it collects zero data and does not disclose this beacon, classify it as suspicious telemetry rather than malicious exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-30T11:05:08.652Z - **Finished:** 2026-10-30T11:06:03.708Z - **Download time:** 1006 ms - **Static scan time:** 218 ms - **AI review time:** 53831 ms - **Total time:** 55056 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:** A transitive dependency implements sampled runtime telemetry for self-hosted widgets. - **Trigger:** Rendering a self-hosted widget, as described in the dependency changelog; the beacon runs on about one render in a thousand when the site key and provider-list override are present. - **Impact:** Prosopo can identify self-hosted installs and their versions. The package README's zero-data claim does not disclose this telemetry, creating a user disclosure concern. - **Evidence paths:** .lpm-dependency-evidence-517c56d3-ba9a-486c-9eb1-5f090ec6acea/3/npm-linux/dist/esm/usageBeacon.js, .lpm-dependency-evidence-517c56d3-ba9a-486c-9eb1-5f090ec6acea/3/npm-linux/CHANGELOG.md, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-30T11:06:03.708Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Sends a GET request to beacon.prosopo.io with the page hostname, site key, bundle version and sample rate. It omits credentials and the referrer; a build-time setting disables it. - **Rationale:** A transitive dependency documents and implements sampled runtime telemetry that reports the page hostname and site key to Prosopo for self-hosted widgets. Because the package README says it collects zero data and does not disclose this beacon, classify it as suspicious telemetry rather than malicious exfiltration. - **Network endpoints:** https://beacon.prosopo.io/v1/b.gif ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The transitive dependency defines a beacon URL containing the page hostname, site key, bundle version and sample rate., The beacon is sent as a GET request to beacon.prosopo.io with credentials and referrer omitted., The dependency changelog says self-hosted widgets send the beacon on about one render in a thousand; the package README says Procaptcha collects zero data. - **Evidence against:** The beacon is limited to self-hosted builds and requires a site key and provider-list override., The beacon is sampled at 0.1% and can be disabled at build time with PROSOPO\_USAGE\_BEACON=false., The package manifest has no install lifecycle scripts. Its runtime entry exports widget components. ## Affected versions and remediation This report applies to @prosopo/procaptcha-react@2.14.16. - Review the evidence and your use of @prosopo/procaptcha-react@2.14.16 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.
