Name of the Vulnerable Software and Affected Versions smb-volume-release versions prior to v3.60.0 CF Deployment versions prior to v56.0.0

Description An input validation bypass exists in the SMB volume mount handling within CloudFoundry Foundation diego-release. This allows a low-privileged CF space developer to bypass the mount-option allowlist and inject arbitrary kernel CIFS mount options, leading to privilege escalation and the bypass of security controls on multi-tenant Diego cells.

Recommendations Update smb-volume-release to version v3.60.0 or later. Update CF Deployment to version v56.0.0 or later.
