- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 0.12.6
- **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.

An automatic install hook alters code in installed ACP and Playwright dependencies. No confirmed credential theft, remote execution, or broad agent-control takeover was identified.

## Security analysis

### Published attack-surface review

- **Summary:** An automatic install hook alters code in installed ACP and Playwright dependencies. No confirmed credential theft, remote execution, or broad agent-control takeover was identified.

- **Trigger:** npm runs the package postinstall hook during installation.

- **Impact:** Dependency behavior can change without a separate user command, creating an install-hook integrity risk.

- **Evidence paths:** package.json, scripts/postinstall.mjs, src/acp-patch.mjs, runner/tools/patch-claude-acp.mjs, src/playwright-patch.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-29T00:50:31.814Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The hook imports patch helpers that locate installed dependency files and write modified source when recognizable patterns are found.

- **Rationale:** The package has an automatic postinstall hook that rewrites dependency source files. This is a real install-hook capability but the inspected code does not prove malicious payload delivery or credential theft.

- **Files touched:** node\_modules/@agentclientprotocol/claude-agent-acp/dist/acp-agent.js, node\_modules/playwright-core/lib/coreBundle.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The package declares an automatic postinstall lifecycle script., The lifecycle script invokes patch routines for an ACP adapter and browser tooling., The ACP patch resolves its installed adapter and rewrites it when its expected source pattern is present., The browser patch rewrites installed Playwright core source when its expected pattern is present.

- **Evidence against:** The inspected agent-login helper constructs an interactive login command and scoped configuration environment., No credential transmission, remote payload retrieval, or destructive action was identified in the inspected install-patch path.
