## Security analysis

### Published attack-surface review

- **Summary:** No confirmed attack was identified in the inspected source. The package downloads and bootstraps its own release through a transparent installer.

- **Trigger:** npm postinstall or invocation of a packaged CLI command.

- **Impact:** Installs and launches the package runtime; inspected code establishes no credential exfiltration or broad agent control mutation.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-30T12:41:16.221Z

### AI review details

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

- **Mechanism:** Downloads a versioned release and checksums, verifies the archive, extracts it, and runs runtime bootstrap with package-local installation settings.

- **Rationale:** The inspected executable source implements package-aligned release installation and CLI forwarding without concrete malicious behavior. Downloaded release code is outside this snapshot, which limits confidence but does not independently establish an attack.

- **Files touched:** .ccb-release, .ccb-install.lock

- **Network endpoints:** https://github.com/SeemSeam/claude\_codex\_bridge/releases/download/v${version}

### Review decision

- **Verdict:** Clean

- **Confidence:** 87.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json runs a transparent release installer through postinstall and declares no runtime self-dependency., The installer defaults to the package project's versioned GitHub release and verifies the downloaded archive against SHA256SUMS., Runtime bootstrap targets the installed release directory and disables role and Neovim installation., The command runner installs the release if needed, then forwards user arguments to the corresponding executable.

- **Evidence against:** Downloaded release contents are absent from this snapshot; their behavior cannot be verified here., The release URL can be overridden through an environment variable, and bootstrap executes the downloaded installer.

## Affected versions and remediation

This report applies to @seemseam/ccb@8.7.1.

- Review the evidence and your use of @seemseam/ccb@8.7.1 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.
