Starting the server automatically downloads and executes external GM extension installers if their markers are absent. This can modify first-party AI-agent extension surfaces without a separate setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-07-23T10:55:40.515Z - **Finished:** 2026-07-23T10:56:36.929Z - **Download time:** 1019 ms - **Static scan time:** 642 ms - **AI review time:** 54752 ms - **Total time:** 56414 ms ## Security analysis ### Published attack-surface review - **Summary:** Starting the server automatically downloads and executes external GM extension installers if their markers are absent. This can modify first-party AI-agent extension surfaces without a separate setup command. - **Trigger:** User starts agentgui server or Electron app. - **Impact:** Remote installer code may alter OpenCode, Gemini, or Kilo agent configuration. - **Evidence paths:** server.js, lib/server-startup.js, lib/gm-agent-configs.js, package.json, lib/http-handler.js, lib/provider-config.js - **Review source:** ai\_review - **Reviewed:** 2026-07-23T10:56:36.929Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic unpinned \`bun x\` agent-extension installation. - **Rationale:** The automatic runtime installation of unpinned AI-agent extensions is a concrete lifecycle risk, but the inspected source does not establish malicious intent or exfiltration. Warn rather than block under the extension-lifecycle policy. - **Files touched:** server.js, lib/server-startup.js, lib/gm-agent-configs.js, package.json, scripts/patch-fsbrowse.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** server startup invokes installGMAgentConfigs() automatically., lib/gm-agent-configs.js runs unpinned \`bun x\` packages gm-oc, gm-gc, and gm-kilo when agent markers are absent., Those markers target OpenCode, Gemini, and Kilo agent-extension directories. - **Evidence against:** postinstall only patches the installed fsbrowse dependency and rebuilds better-sqlite3., No source-confirmed credential exfiltration or non-local C2 endpoint was found., Terminal shell access is disabled unless PASSWORD and ENABLE\_TERMINAL=1 are both set., Provider credentials are displayed masked and written only through the app's explicit auth.save handler. ## Public findings ### 1.
