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. A sandboxed hub can create a temporary LaunchAgent and start a copy of itself outside the sandbox. This is guarded by the sandbox-origin marker and the LaunchAgent does not enable login startup or keep-alive. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-07T20:07:44.015Z - **Finished:** 2026-10-07T20:08:10.382Z - **Download time:** 511 ms - **Static scan time:** 1288 ms - **AI review time:** 24567 ms - **Total time:** 26367 ms The recorded confidence comes from the underlying analysis.

This is guarded by the sandbox-origin marker and the LaunchAgent does not enable login startup or keep-alive. - **Trigger:** A hub launched by a sandboxed backend starts and detects the inherited sandbox-origin marker. - **Impact:** The hub runs as an unsandboxed user process and can continue serving remote access; no malicious use of that capability was established from inspected source. - **Evidence paths:** dist/remote/hub-sandbox.js, dist/bin/hub.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T20:08:10.382Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hub writes a LaunchAgent plist in a temporary directory, bootstraps it into the user's GUI launchd domain, then kickstarts it. - **Rationale:** The sandbox escape via a user LaunchAgent is a real, guarded persistence capability, but source inspection does not establish a concrete attack chain. The package is suspicious and should be warned on rather than blocked. - **Files touched:** dist/remote/hub-sandbox.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** When the hub detects it was started inside the package's sandbox, it attempts to relaunch outside it through launchd., The relaunch creates a temporary LaunchAgent plist and starts the hub; this is persistent process control beyond the current process., The plist disables RunAtLoad and KeepAlive, limiting automatic restart behavior., The hub is normally spawned by the bridge, and the install hook only contacts a token-protected loopback upgrade endpoint. - **Evidence against:** The launchd relaunch is guarded by a sandbox-origin marker and is intended to let the remote hub open a session terminal., The LaunchAgent is started once and does not request launch-at-login or automatic keep-alive., The postinstall notifier uses a configured token and targets loopback only. ## Affected versions and remediation This report applies to zcode-acp-server@0.44.4. - Review the evidence and your use of zcode-acp-server@0.44.4 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.
