CVE-2026-8654: OS Command Injection
Improper input validation in Delphix Continuous Data connectors allows an authenticated user to execute arbitrary operating system commands on the staging or target host.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Remove
Remove
Delphix Continuous Data connectorsfrom your environment.If connectors are not required for operational use, uninstall or remove the Continuous Data connectors from staging and target hosts to eliminate the vulnerable component.
- Configuration
If Continuous Data connectors are not required, disable them to prevent authenticated users from invoking connector functionality that could lead to OS command execution on staging or target hosts.
Delphix Continuous Data connectors enabled = false - Configuration
Review and tighten RBAC and user privileges so authenticated users cannot perform actions that would allow execution of operating system commands on staging or target hosts; remove any unnecessary administrative privileges.
Delphix user accounts / RBAC privileges = least privilege - Compensating control
Restrict network access to connector and management interfaces using firewall rules or ACLs; place staging and target hosts on a segmented network or VLAN and limit connectivity to only trusted systems and administrative IP addresses.
- Operational
Audit logs for signs of unauthorized command execution or misuse of connectors, rotate any credentials that may have been exposed or used by compromised accounts, and rebuild or remediate staging/target hosts if compromise is suspected.
