Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically runs a postinstall notifier and contains runtime code that escapes a macOS Seatbelt sandbox through a LaunchAgent. The escape relaunches a hub as an unsandboxed user process with the inherited environment. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-13T00:53:52.030Z - **Finished:** 2026-09-13T00:55:04.618Z - **Download time:** 758 ms - **Static scan time:** 1113 ms - **AI review time:** 70717 ms - **Total time:** 72588 ms The recorded confidence comes from the underlying analysis.

The escape relaunches a hub as an unsandboxed user process with the inherited environment. - **Trigger:** Installation runs the notifier; later, a macOS hub started with ZCODE\_ACP\_SANDBOX\_ACTIVE invokes the relaunch path. - **Impact:** A constrained agent process can be replaced by an unsandboxed, persistent user-domain process that inherits its environment. - **Evidence paths:** package.json, dist/remote/hub-upgrade-notify.js, dist/remote/hub-sandbox.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T00:55:04.618Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** LaunchAgent-based sandbox escape and process persistence. - **Attack narrative:** After installation, the package contacts a local hub when a configured token exists. Its more serious runtime path detects a macOS sandbox marker, writes a LaunchAgent plist containing inherited environment values, bootstraps it into the user GUI domain, and kickstarts it. This deliberately moves the hub outside the originating Seatbelt sandbox and leaves a launchd-managed process path. - **Rationale:** The source implements a deliberate sandbox escape through launchd and is paired with an automatic install hook. Token gating limits exposure but does not neutralize the permission-bypass behavior. - **Files touched:** package.json, dist/remote/hub-upgrade-notify.js, dist/remote/hub-sandbox.js - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook runs automatically after installation., The hook reads a configured token and sends it to a local upgrade endpoint., On macOS, sandbox-marked execution creates a LaunchAgent to relaunch outside the sandbox., The relaunch preserves the process environment and invokes launchctl bootstrap and kickstart. - **Evidence against:** The install hook targets only 127.0.0.1 and exits when no token is configured., The remote service checks a bearer token before accepting requests. ## Affected versions and remediation This report applies to zcode-acp-server@0.32.0. - Avoid installing zcode-acp-server@0.32.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
