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 has unsafe remote installer behavior reachable through installation and runtime features. The source supports a warning for dangerous capability, but not a malicious-intent block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-09-08T16:03:22.186Z - **Finished:** 2026-09-08T16:06:32.153Z - **Download time:** 507 ms - **Static scan time:** 5389 ms - **AI review time:** 184070 ms - **Total time:** 189967 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:** Installation changes the Electron dependency and runs its installer. During agent use, missing computer-control support can cause a remote script to be piped into a shell. - **Trigger:** npm installation triggers the Electron repair; a computer-control action triggers the driver check and possible installer. - **Impact:** A compromised upstream installer or driver endpoint could execute code with the user's permissions. - **Evidence paths:** package.json, scripts/fix-electron.js, src/main.js, src/agent/computeruse.js, src/agent/tools.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T16:06:32.153Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic remote installer execution and agent-controlled shell capability. - **Rationale:** The package has unsafe remote installer behavior reachable through installation and runtime features. The source supports a warning for dangerous capability, but not a malicious-intent block. - **Files touched:** node\_modules/electron/dist, node\_modules/electron/path.txt, %APPDATA%\\beast\\py, %APPDATA%\\beast\\skills/\ - **Network endpoints:** https://npmmirror.com/mirrors/electron/, https://cua.ai/driver/install.ps1, https://cua.ai/driver/install.sh, https://www.python.org/ftp/python/3.12.8/python-3.12.8-embed-amd64.zip, https://bootstrap.pypa.io/get-pip.py, https://raw.githubusercontent.com/searxng/searxng/master/requirements.txt, https://github.com/searxng/searxng/archive/refs/heads/master.zip, https://raw.githubusercontent.com/algokodcom/beast-agent/main/store/skills.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The install lifecycle automatically invokes an Electron repair script., That repair deletes Electron files and runs Electron's installer, with a third-party mirror fallback., A computer-control action is reachable from the main application and can pipe a remote driver installer into a shell., The agent can download and unpack an embedded Python runtime, and exposes arbitrary PowerShell commands., The explicit SearXNG setup path downloads bootstrap code and installs remote Python packages., The skill store fetches a remote index and writes supplied skill files locally. - **Evidence against:** No runtime dependency on beast-agent itself was found., The SearXNG and package-update installers require explicit CLI subcommands., The Electron repair targets its own Electron dependency rather than consumer project files., The inspected webhook listener binds only to localhost and checks a token. ## Affected versions and remediation This report applies to beast-agent@2.17.0. - Review the evidence and your use of beast-agent@2.17.0 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.
