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. The automatic installer accepts platform executable archives without validating TLS certificates or archive integrity. This establishes a substitution risk, but no intentional attack was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-30T17:14:32.634Z - **Finished:** 2026-09-30T17:15:54.278Z - **Download time:** 1279 ms - **Static scan time:** 42 ms - **AI review time:** 80322 ms - **Total time:** 81644 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:** The automatic installer accepts platform executable archives without validating TLS certificates or archive integrity. This establishes a substitution risk, but no intentional attack was confirmed. - **Trigger:** Installation on a non-Windows platform without an existing platform binary, followed by CLI invocation. - **Impact:** A substituted executable could run with the invoking user's permissions. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-09-30T17:15:54.278Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** An attacker intercepting the download could substitute an archive whose executable is subsequently launched by the CLI. - **Rationale:** Unauthenticated executable distribution warrants a warning for potential remote code execution. Package-local setup and user-invoked execution do not establish malicious intent or a blocking attack chain. - **Files touched:** bin/.onecode, .platform-version, .platform-bootstrap-work, .opencode, .oneskills - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** package.json automatically invokes postinstall.mjs, which calls the platform bootstrap., platform-bootstrap.mjs downloads platform archives from https://218.90.133.98:4443/onecode\_tgz., The downloader disables TLS certificate verification., Downloaded archives are extracted without an integrity check, and bin/onecode executes the selected platform binary. - **Evidence against:** Inspected mutations are confined to the package root and its platform dependency., No credential harvesting, exfiltration, runtime self-dependency, or broad agent configuration mutation was found., The platform binary is launched when the user invokes the CLI; malicious payload content was not established. ## Affected versions and remediation This report applies to @onescience/onecode@1.14.50-202609201758. - Review the evidence and your use of @onescience/onecode@1.14.50-202609201758 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.
