The packaged JavaScript itself contains no confirmed data theft or agent-control mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-11T20:42:30.823Z - **Finished:** 2026-08-11T20:43:13.231Z - **Download time:** 503 ms - **Static scan time:** 104 ms - **AI review time:** 41799 ms - **Total time:** 42408 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the npm package fetches an opaque platform archive and executes its extracted bootstrap script. The packaged JavaScript itself contains no confirmed data theft or agent-control mutation. - **Trigger:** npm postinstall - **Impact:** A compromised or redirected release payload can execute with the installing user's permissions. - **Evidence paths:** package.json, bin/ccb-npm-install.js, bin/ccb-npm-runner.js, bin/ccb.js, bin/ask.js, bin/autonew.js, bin/ctx-transfer.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T20:43:13.231Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote archive download, extraction, and bash execution - **Rationale:** The source establishes unconsented install-time remote code execution, but the observed default endpoint is package-aligned and no direct malicious action is present in the shipped wrappers. This warrants a warning rather than a publication block. - **Files touched:** bin/ccb-npm-install.js, .ccb-release, .ccb-install.lock - **Network endpoints:** https://github.com/SeemSeam/claude\_codex\_bridge/releases/download/v${version} ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** npm postinstall downloads and extracts a remote release archive., Postinstall executes the downloaded archive's install.sh with bash., Archive checksum is fetched from the same mutable release location; no pinned digest/signature., CCB\_NPM\_RELEASE\_BASE\_URL can redirect the install-time payload source. - **Evidence against:** Default payload host is the package-aligned SeemSeam GitHub release URL., Inspected wrapper code shows no credential harvesting, exfiltration, or foreign agent-config writes., Writes are scoped to the package directory and a temporary directory. ## Public findings ### 1.
