No credential theft, foreign agent-config writes, or unrelated network sink is present in the published JavaScript. - **Trigger:** npm install runs postinstall; user-invoked ccb, ask, autonew, or ctx-transfer also call the same installer before spawning the extracted binary. - **Impact:** No confirmed malicious impact in the published package source. - **Review source:** ai\_review - **Reviewed:** 2026-09-19T03:59:14.892Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Package-aligned GitHub release download and local runtime bootstrap - **Rationale:** Readable postinstall code downloads the same-version GitHub release for this CLI, checks SHA256SUMS, and bootstraps under .ccb-release with role install disabled. Scanner malware fingerprints are a noisy match to that downloader shape, not a concrete attack in this source. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has a postinstall that runs bin/ccb-npm-install.js, with no runtime dependencies and no self-dependency on another @seemseam/ccb release., The installer downloads the matching-version archive and SHA256SUMS from the GitHub SeemSeam/claude\_codex\_bridge release (or operator CCB\_NPM\_RELEASE\_BASE\_URL), checks the digest, and extracts under the package .ccb-release directory., Runtime bootstrap runs the vendored install.sh runtime-bootstrap with CCB\_INSTALL\_ROLES and CCB\_INSTALL\_NEOVIM set to 0, so it does not enable role or neovim install from this hook., CLI shims only call that installer then spawn the extracted executable; inspectable JS has no eval, credential harvest, or agent-config writes., Scanner malware-fingerprint hits match this native-release downloader shape, not a hidden payload or unrelated exfil sink in the published source. - **Evidence against:** Static scanner labeled the installer similar to a previously blocked package., SHA256SUMS is fetched from the same remote as the tarball rather than pinned inside the npm package., postinstall follows HTTPS redirects and then runs bash on install.sh from the downloaded archive. ## Affected versions and remediation This report applies to @seemseam/ccb@8.6.19. - Review the evidence and your use of @seemseam/ccb@8.6.19 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.
