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. An explicit CLI setup command modifies the consumer project's lifecycle scripts. Those scripts can subsequently scan dependencies and report a manifest to Patchstack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-09T10:34:26.354Z - **Finished:** 2026-09-09T10:35:55.733Z - **Download time:** 1008 ms - **Static scan time:** 3957 ms - **AI review time:** 84412 ms - **Total time:** 89379 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:** An explicit CLI setup command modifies the consumer project's lifecycle scripts. Those scripts can subsequently scan dependencies and report a manifest to Patchstack. - **Trigger:** The user runs patchstack-connect setup in a project. - **Impact:** Future dependency installs and builds can run Patchstack commands and disclose dependency inventory data to the configured Patchstack endpoint. - **Evidence paths:** dist/cli.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-09T10:35:55.733Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked lifecycle-hook installation and manifest reporting. - **Rationale:** The package is not malicious on the inspected evidence because it lacks an automatic registry install hook and its metadata-address handling is defensive. It remains suspicious because its explicit setup command persistently alters consumer lifecycle scripts and enables recurring network reporting. - **Files touched:** package.json, .patchstackrc.json, .patchstackrc.local.json, .gitignore - **Network endpoints:** api.patchstack.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The explicit setup command changes a consumer project's install and build lifecycle scripts., The added postinstall command can later scan dependency data and send a manifest to Patchstack., The scan flow stores a server-issued API credential in project-local configuration. - **Evidence against:** The package manifest has no preinstall, install, or postinstall hook; its prepare script is a build command., Project mutation is reached through the user-invoked setup CLI command, not import-time execution., The cloud metadata indicators are used to identify and block internal destinations for SSRF protection, not to retrieve metadata. ## Affected versions and remediation This report applies to @patchstack/connect@0.5.0. - Review the evidence and your use of @patchstack/connect@0.5.0 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.
