Review signals: 1 connection review, 13 download and execute, 4 hardcoded secret, 14 known vulnerability, 1 outside write, 1 sensitive read. 22 static matches retained as context.

Repository processes attempted these non-loopback connections; proxies can hide the final hostname. <internal-ip>:58162 2 attributed processes.

Source contains download and execute; review its purpose. 3 distinct locations. 13 findings.

Gitleaks found a possible hardcoded secret; value withheld. docs/API.md 4 findings.

OSV reports a known vulnerability in this dependency version. 4 distinct locations. 14 findings.

Repository processes attempted these writes outside documented output/cache paths. 3 distinct locations. 30 attributed processes.

A repository process attempted to read this sensitive path. /etc/shadow 18 attributed processes.

13 download and execute matches retained as context; full list in the evidence.

9 hardcoded secret matches retained as context; full list in the evidence.

OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.

A short run cannot establish that code is safe.

Connections show IP addresses; proxies can hide the final hostname.

Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.
