What happened

CVE-2026-85184, rated CVSS 8.8, let Goose 1.37.0 execute arbitrary commands from a malicious recipe extension, bypassing the agent framework's own security scan.

Why it matters

Teams running Goose should patch or restrict where recipes come from, since an attacker gets command execution as the running user and the built-in scan does not stop it.
