CVE-2026-26358
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell Unisphere for PowerMax, version(s) 10.2, contain(s) a Missing Authorization vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceDell Unisphere for PowerMax version 10.2 contains a missing authorization vulnerability that allows a low-privileged remote attacker to bypass access controls and gain unauthorized access to functionality or data within the storage management interface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Dell Unisphere for PowerMax is deployedIdentify whether Dell Unisphere for PowerMax storage management software is installed in your environment. This is typically deployed as a virtual appliance or on dedicated hardware for managing PowerMax storage arrays.Affected if The product is present in your environment and has not been upgraded to version 10.3.0.1 or later.
-
Identify the installed versionAccess the Unisphere management interface and navigate to the About or System Information section to view the installed version number. Alternatively, check the system documentation or use the Unisphere CLI 'about' command if available.Affected if The displayed version is earlier than 10.3.0.1 (for example, 10.2.x, 10.1.x, or earlier).
-
Compare version against affected rangeDocument the exact version number found and compare it against the affected range: any version less than 10.3.0.1 is vulnerable.Affected if The installed version falls below 10.3.0.1 (for example, 10.2.0.0, 10.2.0.1, 10.1.0.0).
-
Assess network accessibilityDetermine whether the Unisphere management interface is accessible from network segments outside of the dedicated administration network. Check firewall rules, exposed interfaces, and access paths.Affected if The Unisphere interface is network-accessible to untrusted users or segments, as this enables the low-privileged remote attacker to attempt the authorization bypass.
You are affected if Dell Unisphere for PowerMax is running version 10.3.0.0 or earlier and the management interface is network-accessible to the attacker.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped10.3.0.1
Apply the vendor-provided patch or hotfix for CVE-2026-26358 when released. In the interim, implement network segmentation to restrict access to Unisphere management interfaces to only authorized administration networks, and review user role assignments to ensure least privilege.
10.3.0.1
- Upgrade Dell Unisphere for PowerMax to version 10.3.0.1 or later
