This report does not record a matching static-policy override reason. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed malicious attack surface was established. The package reports configured security data to its vendor and can modify project scripts only through an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-12T10:05:55.568Z - **Finished:** 2026-09-12T10:07:09.408Z - **Download time:** 764 ms - **Static scan time:** 2262 ms - **AI review time:** 70812 ms - **Total time:** 73840 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:** No confirmed malicious attack surface was established. The package reports configured security data to its vendor and can modify project scripts only through an explicit setup command. - **Trigger:** A user runs the CLI setup or scan command, or enables configured runtime protection. - **Impact:** It may send dependency and site metadata to Patchstack and add scan commands to a user project after explicit setup. - **Review source:** ai\_review - **Reviewed:** 2026-09-12T10:07:09.408Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Configured vendor manifest reporting and explicit project build-hook wiring. - **Rationale:** The scanner's network and metadata findings correspond to the package's security-monitoring and SSRF-blocking functions. Although setup can add lifecycle commands to a consumer project, this occurs only after an explicit CLI command and the package itself has no registry install hook. - **Files touched:** package.json - **Network endpoints:** api.patchstack.com ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason. - **Evidence for AI clean decision:** The runtime entrypoints can post a dependency manifest, site URL, and site name to Patchstack., The explicit \`setup\` command rewrites the consumer project's lifecycle scripts to run scans., The metadata-host finding is a defensive SSRF rule that blocks internal destinations., The manifest has no preinstall, install, or postinstall hook; its only lifecycle hook is prepare. - **Evidence against:** No import-time execution was found in the library entrypoints., Reporting is tied to configured runtime protection or explicit CLI commands., No self-dependency, shell execution, credential harvesting beyond Patchstack configuration, or foreign AI-agent configuration writes were found. ## Affected versions and remediation This report applies to @patchstack/connect@0.5.3. - Review the evidence and your use of @patchstack/connect@0.5.3 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.
