This vulnerability involves improper neutralization of argument delimiters (CWE-88) in the SMB volume mount handling of CloudFoundry Foundation's diego-release. Specifically, it allows a low-privileged user to inject arbitrary kernel CIFS mount options by bypassing the mount-option allowlist. This can lead to privilege escalation and bypass of security controls in multi-tenant environments. The affected components are smb-volume-release versions before v3.60.0 and CF Deployment versions before v56.0.0. No CVSS score or official remediation level is provided, and no known exploits are reported in the wild.

The vulnerability allows a low-privileged Cloud Foundry space developer to escalate privileges and bypass security controls on multi-tenant Diego cells by injecting arbitrary kernel CIFS mount options. This could compromise the isolation and security of multi-tenant deployments, potentially leading to unauthorized access or control over system resources.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should upgrade smb-volume-release to version 3.60.0 or later and CF Deployment to version 56.0.0 or later once official patches or updates are released. Until then, restrict permissions for space developers and monitor for unusual mount option usage as a precaution.
