Unisphere for PowerMax: Deserialization of Untrusted Data
CVE-2026-54469 is a high-severity deserialization of untrusted data vulnerability in Unisphere for PowerMax from Dell, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 10.3.0.7 or later, 10.3.1.1 Patch 11360 or later as the first without the flaw, so updating Unisphere for PowerMax to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.86% chance of exploitation within 30 days, higher than 59% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Unisphere for PowerMax to 10.3.0.7 or later or 10.3.1.1 Patch 11360 or later, whichever matches your release line, or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
Affected products and versions

Official description
Dell Unisphere for PowerMax, version(s) 10.3.0.5 and prior, contain(s) a Deserialization of Untrusted Data vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to arbitrary command execution with root privileges.

The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
