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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-08-27T06:54:27.944Z - **Finished:** 2026-08-27T06:55:27.053Z - **Download time:** 508 ms - **Static scan time:** 6789 ms - **AI review time:** 51810 ms - **Total time:** 59109 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:** This is an agent gateway with privileged, administrator-invoked application installation and Claude execution. Its install hook installs dependencies only beneath the bundled MCP directory; no unconsented mutation of a foreign agent configuration was found. - **Trigger:** An administrator calls the application-install API, or an operator starts a configured agent workflow. - **Impact:** A trusted administrator can intentionally introduce and run external application or agent code; this is a real high-privilege capability, not a confirmed malicious chain. - **Evidence paths:** package.json, dist/api/apps-router.js, dist/apps/installer.js, dist/api/router.js, dist/session/process.js, dist/api/workspace-router.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T06:55:27.053Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated agent orchestration, external app installation, and Claude subprocess execution. - **Rationale:** The package is not confirmed malicious, but it deliberately provides high-impact agent and application execution capabilities. The lifecycle script alone does not meet the block policy because it does not mutate a foreign or broad AI-agent control surface. - **Files touched:** mcp/, ~/.claude-gateway/agents/\/workspace/, \/.sessions/\/mcp-config.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The install hook runs Bun dependency installation in the bundled MCP directory., The authenticated admin API can install applications from a selected GitHub repository and commit., The gateway can launch Claude with permission checks disabled as part of its agent workflow. - **Evidence against:** No source showed secret harvesting or transmission to an untrusted package-owned receiver., Slack token traffic is limited to Slack's token-validation endpoint., Agent workspace and skill writes require authenticated API access; workspace filenames are allowlisted., The package reads Claude settings for MCP configuration but does not write that foreign configuration. ## Affected versions and remediation This report applies to @0xmaxma/claude-gateway@1.8.1. - Review the evidence and your use of @0xmaxma/claude-gateway@1.8.1 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.
