Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Inspected sources are a first-party npm wrapper that vendors the matching GitHub release into the package tree and bootstraps a managed runtime there. No credential theft, foreign agent-control writes, nested self-install chain, or obfuscated dropper remains in this package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-17T10:06:10.335Z - **Finished:** 2026-09-17T10:07:47.544Z - **Download time:** 256 ms - **Static scan time:** 72 ms - **AI review time:** 96880 ms - **Total time:** 97209 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:** Inspected sources are a first-party npm wrapper that vendors the matching GitHub release into the package tree and bootstraps a managed runtime there. No credential theft, foreign agent-control writes, nested self-install chain, or obfuscated dropper remains in this package. - **Trigger:** npm install runs postinstall; later ccb/ask/autonew/ctx-transfer commands reuse the vendored binary. - **Impact:** No confirmed malicious impact from the shipped package source. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T10:07:47.544Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** version-matched GitHub release bootstrap inside the package directory - **Rationale:** The postinstall downloader is package-aligned for this CLI and stays inside the package vendor directory with checksum verification and no self-dependency. Scanner malware fingerprints match that wrapper shape, not a concrete attack in this release. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** postinstall runs bin/ccb-npm-install.js, which downloads a GitHub release tarball and SHA256SUMS, extracts under .ccb-release, then runs bash install.sh runtime-bootstrap., CLI bins call that installer and spawn the extracted executable., Scanner malware-similarity hits are this same transparent wrapper, not hidden payload code. - **Evidence against:** package.json has no dependencies or self-dependency lifecycle chain., Download URL is the first-party SeemSeam/claude\_codex\_bridge GitHub release for this version, with a SHA256 check., Bootstrap is scoped to the package vendor dir and turns off roles and neovim install., Shipped JS has no eval, env harvesting, foreign agent-config writes, or obfuscation., ask.js is a static wrapper, not a dynamic require gadget. ## Affected versions and remediation This report applies to @seemseam/ccb@8.6.18. - Review the evidence and your use of @seemseam/ccb@8.6.18 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.
