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:** 0.1.23 - **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 unprompted global update creates a conditional code-execution risk, so a warning is warranted. The inspected source does not establish malicious update content or another concrete attack chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-13T05:13:01.236Z - **Finished:** 2026-10-13T05:14:41.949Z - **Download time:** 780 ms - **Static scan time:** 274 ms - **AI review time:** 99659 ms - **Total time:** 100713 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 launcher can update the globally installed package without user confirmation. This creates a conditional path for newer package code to run with the user’s privileges. - **Trigger:** Running a package launcher when its update check reports a newer version. - **Impact:** A package update may execute new code under the user’s account. - **Evidence paths:** package.json, dist/launcher.js - **Review source:** ai\_review - **Reviewed:** 2026-10-13T05:14:41.949Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher starts a detached global npm install for this package. - **Rationale:** The unprompted global update creates a conditional code-execution risk, so a warning is warranted. The inspected source does not establish malicious update content or another concrete attack chain. ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes dist/launcher.js through its command-line entrypoints., Each launcher run checks for an update before normal startup., When a newer version is reported, the launcher starts a detached global npm install of the package without asking the user; the installed code can then execute with the user’s privileges. - **Evidence against:** The update installation is conditional on the reported version being newer; source inspection did not establish that an update is malicious. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.23. - Review the evidence and your use of @funny-booth/agent-core@0.1.23 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.
