An unconsented lifecycle hook changes a foreign AI-agent control surface and its message flow. - **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:** 0.6.0 - **Selected version is latest:** No - **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. Installing the package automatically modifies a third-party Claude ACP adapter. The change forwards agent prompt-suggestion data into this package's Kai metadata channel. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-12T22:47:27.035Z - **Finished:** 2026-09-12T22:48:29.850Z - **Download time:** 773 ms - **Static scan time:** 1082 ms - **AI review time:** 60959 ms - **Total time:** 62815 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:** Installing the package automatically modifies a third-party Claude ACP adapter. The change forwards agent prompt-suggestion data into this package's Kai metadata channel. - **Trigger:** npm install, including a noninteractive dependency installation. - **Impact:** An unconsented lifecycle hook changes a foreign AI-agent control surface and its message flow. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/acp-patch.mjs, runner/tools/patch-claude-acp.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T22:48:29.850Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall source patching of a third-party AI-agent adapter. - **Attack narrative:** On installation, npm runs scripts/postinstall.mjs, which invokes ensureClaudeAcpPatched without requiring an interactive or global install. The patch resolver finds the installed @agentclientprotocol/claude-agent-acp adapter and rewrites its compiled acp-agent.js. The injected code forwards prompt suggestions through a Kai-specific metadata channel. This is an automatic modification of a foreign AI-agent component rather than package-local setup. - **Rationale:** The automatic postinstall mutation of a third-party AI-agent adapter is a concrete unconsented control-surface change. Its narrow and readable implementation reduces ambiguity but does not remove the install-hook abuse. - **Files touched:** scripts/postinstall.mjs, src/acp-patch.mjs, runner/tools/patch-claude-acp.mjs, node\_modules/@agentclientprotocol/claude-agent-acp/dist/acp-agent.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall script on every npm installation., The postinstall script unconditionally invokes a patch routine before its interactive-only setup check., That routine resolves the third-party Claude ACP dependency and patches its compiled agent file., The patch rewrites the adapter to forward prompt suggestions into Kai metadata, altering an AI-agent communication path automatically. - **Evidence against:** The lifecycle script does not itself create the background service; that setup is gated on an interactive global install., The inspected patch is readable and narrowly targeted rather than obfuscated. ## Affected versions and remediation This report applies to @gleapai/kai-bridge@0.6.0. - Avoid installing @gleapai/kai-bridge@0.6.0. 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.
