CVE-2026-47829: Argument Injection in BOSH CLI Allows Local Command Execution on Operator Workstations via Compromised Director

High 7.7 EPSS 0.4% OpenSSH

Argument Injection in bosh-cli allows a compromised BOSH Director to inject arbitrary OpenSSH options into the locally-spawned ssh process when an operator runs bosh ssh -c, bosh logs -f, or other non-interactive SSH paths, leading to local command execution on the operator's workstation. Affected versions: bosh-cli versions prior to v7.10.4.
