Security readout for executives and security teams
Plain-English summary
Dell reports a high-severity missing authorization issue in Dell Unisphere for PowerMax version 10.2. A low-privileged remote user could potentially gain unauthorized access. For organizations using this storage management platform, the concern is unauthorized access to sensitive management functions or data.
Executive priority
Treat as a high-priority storage management risk if Unisphere for PowerMax 10.2 is in use. Unauthorized access to management systems can affect sensitive data and operational resilience. Validate exposure and follow Dell guidance promptly.
Technical view
CVE-2026-26358 is a CWE-862 Missing Authorization vulnerability affecting Dell Unisphere for PowerMax 10.2. The CVSS v3.1 score is 8.8, with network attack vector, low complexity, low privileges required, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most relevant where Dell Unisphere for PowerMax 10.2 is deployed and reachable by low-privileged authenticated users over a network. The provided data does not confirm exposure for other versions or products.
Exploitation context
The CVE record states a low-privileged attacker with remote access could potentially exploit the flaw. CISA KEV is false in the provided bundle, and no cited source states active exploitation.
Researcher notes
The public bundle identifies the weakness class, CVSS vector, and affected version 10.2, but does not include detailed authorization boundaries, endpoints, proof-of-concept status, or fixed versions. Avoid assuming impact beyond the CVE description and Dell advisory.
Mitigation direction
- Review Dell advisory DSA-2026-102 for affected versions and remediation guidance.
- Prioritize remediation for internet-accessible or broadly reachable Unisphere deployments.
- Restrict access to Unisphere management interfaces to trusted administration networks.
- Review low-privileged account access until vendor guidance is applied.
Validation and detection
- Inventory Dell Unisphere for PowerMax deployments.
- Confirm whether version 10.2 is present.
- Check network reachability to Unisphere management interfaces.
- Review Dell advisory for exact fixed versions or vendor-directed mitigations.
- Audit recent low-privileged user activity for unexpected access patterns.
