CVE-2026-41013: CWE-88 Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in CloudFoundry Foundation smb-volume-release
Input validation bypass in SMB volume mount handling in CloudFoundry Foundation diego-release allows low-privileged CF space developer to inject arbitrary kernel CIFS mount options via bypassing the mount-option allowlist, enabling privilege escalation and security control bypass on multi-tenant Diego cells. Affected versions: smb-volume-release: All versions prior to v3.60.0 CF Deployment: All versions prior to v56.0.0
AI Analysis
Technical Summary
This vulnerability arises from insufficient input validation in the SMB volume mount handling of CloudFoundry Foundation's diego-release, specifically in the smb-volume-release component. It allows an attacker with low privileges within a Cloud Foundry space to inject arbitrary kernel CIFS mount options by bypassing the mount-option allowlist. This injection can lead to privilege escalation and security control bypass on multi-tenant Diego cells. The issue is tracked as CVE-2026-41013 with a CVSS score of 8.1 (high severity). Affected versions include all smb-volume-release versions before v3.60.0 and CF Deployment versions before v56.0.0. No patch or official remediation guidance is currently available.
Potential Impact
Successful exploitation 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 compromises the confidentiality and integrity of the affected system components. Availability impact is not indicated.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to Cloud Foundry space developer roles to trusted users only and monitor for unusual mount option configurations. Avoid deploying affected versions in sensitive environments where privilege escalation risk is unacceptable.
