Installed coding agents can automatically expose Wayari tools in future sessions. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.5.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installation automatically registers Wayari as a global MCP server with installed Claude Code and Codex clients. This changes broad AI-agent control surfaces without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T00:37:01.791Z - **Finished:** 2026-09-15T00:38:06.440Z - **Download time:** 510 ms - **Static scan time:** 4316 ms - **AI review time:** 59822 ms - **Total time:** 64649 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 automatically registers Wayari as a global MCP server with installed Claude Code and Codex clients. This changes broad AI-agent control surfaces without an explicit user command. - **Trigger:** npm installation, via postinstall. - **Impact:** Installed coding agents can automatically expose Wayari tools in future sessions. - **Evidence paths:** package.json, dist/cli-postinstall.mjs, dist/wayari.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-15T00:38:06.440Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes a CLI command that registers global MCP integrations. - **Attack narrative:** The manifest launches a postinstall script. That script synchronously runs the package CLI with \`connect\`, which registers Wayari as an MCP server for any detected Claude Code and Codex installation. Claude is explicitly registered at user scope and Codex globally. This occurs during installation rather than after an explicit user command, mutating broad third-party AI-agent control surfaces. - **Rationale:** The automatic lifecycle chain performs unconsented global AI-agent MCP registration. This is concrete install-hook abuse even though no secret theft or network exfiltration was found in that path. - **Files touched:** ~/.claude/settings.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall lifecycle hook., The lifecycle hook automatically runs \`wayari connect\`., Connect registers a global MCP server for Claude Code and Codex through their CLIs., Registration is executed through a login shell without user confirmation. - **Evidence against:** No relevant network endpoint or secret exfiltration was found in the installation path., The registration commands target named agent CLIs rather than directly editing their config files. ## Affected versions and remediation This report applies to wayari@0.5.0. - Avoid installing wayari@0.5.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
