Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.12.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. LPM treats this as warn-only first-party agent extension lifecycle risk. An install-time hook modifies a bundled AI-agent adapter so predicted prompts are forwarded into this package's runner. No confirmed external recipient was found in the inspected path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-27T18:40:57.370Z - **Finished:** 2026-09-27T18:42:16.491Z - **Download time:** 763 ms - **Static scan time:** 1333 ms - **AI review time:** 77025 ms - **Total time:** 79121 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:** An install-time hook modifies a bundled AI-agent adapter so predicted prompts are forwarded into this package's runner. No confirmed external recipient was found in the inspected path. - **Trigger:** npm postinstall runs automatically during installation. - **Impact:** Predicted user prompt content becomes available to the package runner without a separate user action. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/acp-patch.mjs, runner/tools/patch-claude-acp.mjs, runner/acp-runner.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T18:42:16.491Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes a source patch that forwards prompt suggestions, and the runner emits the suggestion text as an event. - **Rationale:** Automatic modification of an AI-agent adapter to capture and relay prompt suggestions is a concrete capability risk. The inspected source does not prove external exfiltration or a blocking attack. - **Files touched:** scripts/postinstall.mjs, src/acp-patch.mjs, runner/tools/patch-claude-acp.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package declares an automatic postinstall hook., The postinstall hook loads and runs a Claude ACP patch., The patch changes the adapter to forward predicted user prompts to the Kai runner., The runner emits those forwarded prompts as events. - **Evidence against:** No network recipient or transmission sink for the emitted prompt events was confirmed in the inspected evidence., The patch targets the package-resolved ACP adapter rather than a broad user agent configuration. ## Affected versions and remediation This report applies to @gleapai/kai-bridge@0.12.3. - Review the evidence and your use of @gleapai/kai-bridge@0.12.3 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.
