This vulnerability (CVE-2026-41857) involves improper neutralization of special elements used in OS commands (CWE-78) in the CloudFoundry BOSH CLI. Specifically, when an operator runs commands such as bosh ssh, bosh scp, or bosh logs -f with default flags, a compromised or malicious BOSH Director can inject and execute arbitrary shell commands on the operator's workstation. The issue affects BOSH CLI versions prior to 7.10.5. The CVSS 4.0 score is 7.1, indicating high severity. No vendor advisory or patch information is currently available, and the vulnerability is not related to a cloud service.

If exploited, this vulnerability allows a compromised or malicious BOSH Director to execute arbitrary shell commands on the operator's workstation, potentially leading to unauthorized access, data compromise, or further system compromise. The attack requires the operator to run specific BOSH CLI commands with default flags, which could lead to privilege escalation or system control on the operator's machine.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, operators should exercise caution when running bosh ssh, bosh scp, or bosh logs -f commands, especially when interacting with untrusted or potentially compromised BOSH Directors. Monitoring vendor channels for updates and applying patches promptly once released is recommended.
