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. No automatic install-time attack was confirmed. On explicit CLI use, the obfuscated launcher can start a bundled platform executable and the library contains broad file, process, and HTTP primitives. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 73.0% - **Started:** 2026-09-14T00:12:48.642Z - **Finished:** 2026-09-14T00:13:49.414Z - **Download time:** 755 ms - **Static scan time:** 892 ms - **AI review time:** 59124 ms - **Total time:** 60772 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:** No automatic install-time attack was confirmed. On explicit CLI use, the obfuscated launcher can start a bundled platform executable and the library contains broad file, process, and HTTP primitives. - **Trigger:** A user runs cxu or imports and calls its library APIs. - **Impact:** The opaque implementation makes the scope of runtime file, process, and network actions difficult to independently verify. - **Evidence paths:** package.json, dist/index.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T00:13:49.414Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated launcher and agent-style file/process/HTTP capability bundle. - **Rationale:** No concrete malicious install-time behavior or exfiltration was established, so a block is not justified. The intentionally opaque implementation combined with broad agent-like capabilities is a real unresolved supply-chain risk. ### Review decision - **Verdict:** Suspicious - **Confidence:** 73.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Published JavaScript is heavily obfuscated, including a runtime string decoder, which prevents reliable review of its broad file, process, and HTTP capabilities., The package exposes both an import entrypoint and an executable CLI; the obfuscated bundle imports child-process and filesystem write/delete APIs., The CLI starts a platform-specific standalone executable and can invoke installers after explicit user interaction or a --yes option. - **Evidence against:** package.json has no preinstall, install, postinstall, or other lifecycle hook., No fixed external endpoint, credential-harvesting path, or automatic network exfiltration was confirmed., The observed launcher behavior is activated by an explicit cxu command rather than package installation. ## Affected versions and remediation This report applies to @codex-ultra/cxu@0.2.7. - Review the evidence and your use of @codex-ultra/cxu@0.2.7 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.
