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 middleware sends request and query payload fields to its configured service, but its scrubber only handles selected credential keys and known PII patterns. Since the README describes transmission as metadata, the unfiltered fields create an undisclosed collection risk; the behavior is request-triggered and the destination is configurable, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-11-04T05:16:37.185Z - **Finished:** 2026-11-04T05:17:39.071Z - **Download time:** 510 ms - **Static scan time:** 122 ms - **AI review time:** 61253 ms - **Total time:** 61886 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 middleware may send unrecognized request and query data as runtime telemetry despite describing transmission as metadata. - **Trigger:** An application calls \`privguard()\` and a handled request completes. - **Impact:** Fields that the scrubber does not recognize can be transmitted without the README’s stated metadata-only limitation. - **Evidence paths:** privguard-middleware.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-04T05:17:39.071Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It combines \`req.body\` and \`req.query\`, applies limited PII scrubbing, and posts the resulting payload to the configured PrivGuard endpoint. - **Rationale:** The middleware sends request and query payload fields to its configured service, but its scrubber only handles selected credential keys and known PII patterns. Since the README describes transmission as metadata, the unfiltered fields create an undisclosed collection risk; the behavior is request-triggered and the destination is configurable, so this warrants a warning rather than a block. - **Files touched:** privguard-middleware.js, README.md, package.json - **Network endpoints:** http://localhost:5000/api/events/batch (default; host is configurable) ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The middleware combines request body and query fields, then includes the sanitized payload in the event it sends., It posts events to \`/api/events/batch\` at a configurable URL, defaulting to \`http://localhost:5000\`., The README describes the outbound data as metadata after local PII scrubbing., The package has no install hook; it exports middleware that runs when an application uses it. - **Evidence against:** The package’s stated purpose is compliance monitoring, and its README describes asynchronous event batching., The outbound destination can be configured by the application, and the default is localhost., The middleware is activated by an application request, not by package installation or import. ## Affected versions and remediation This report applies to privguard-sdk@1.0.0. - Review the evidence and your use of privguard-sdk@1.0.0 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.
