Workarounds & Mitigations
| CVE ID | Workaround and Mitigation |
| CVE-2026-22271 | To mitigate this vulnerability, customers on all supported ECS or Objectscale versions, still using default credentials, can apply the password change procedure documented as a 'NOTE' under the ‘Default Node Users’ table in the Dell ObjectScale 4.2.0.0 Security Configuration Guide, without performing an upgrade. |
| CVE-2026-22273 |
To remediate this vulnerability, starting with ObjectScale version 4.2.0.0, the system automatically disables CAS unless it detects active usage. To mitigate this vulnerability, customers who have not upgraded to ObjectScale version 4.2.0.0 yet or are actively using CAS in their setup should refer to the ‘Securing the CAS Protocol’ section in the Dell ObjectScale 4.2.0.0 Security Configuration Guide and apply the recommended steps. |
