Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 16 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 0.1.135 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 package creates a concrete automatic remote-code-execution supply-chain risk, but the inspected source does not establish malicious payload content or hostile intent. This warrants a warning rather than a publication block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-13T21:16:33.439Z - **Finished:** 2026-09-13T21:17:19.378Z - **Download time:** 252 ms - **Static scan time:** 14 ms - **AI review time:** 45672 ms - **Total time:** 45939 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 global install automatically executes an unsigned remote shell script. That script can run arbitrary commands and provide the executable copied into the installed package. - **Trigger:** Global npm or Bun installation on a non-Windows system outside CI. - **Impact:** A compromised or changed swirls.ai install endpoint can execute arbitrary code with the installing user's privileges. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T21:17:19.378Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall remote shell execution through curl piped to Bash. - **Rationale:** The package creates a concrete automatic remote-code-execution supply-chain risk, but the inspected source does not establish malicious payload content or hostile intent. This warrants a warning rather than a publication block. - **Files touched:** $HOME/.local/bin/swirls, bin/swirls - **Network endpoints:** https://swirls.ai/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The manifest automatically runs a postinstall script., On global non-Windows installs, the script downloads a remote URL and pipes it directly to Bash., The installer replaces the package executable with a binary from the user's local bin directory. - **Evidence against:** The trigger is limited to global npm or Bun installation and skips CI and Windows., The inspected files contain no secret harvesting, data exfiltration, self-dependency, or AI-agent configuration changes. ## Affected versions and remediation This report applies to @swirls/cli@0.1.135. - Review the evidence and your use of @swirls/cli@0.1.135 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.
