PowerStore 500T: Improper Neutralization of Special Elements used in a Command
CVE-2026-79682 is a high-severity improper neutralization of special elements used in a command vulnerability in PowerStore 500T from Dell, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 4.1.0.6-2771237 or later, 4.3.1.2-2771239 or later as the first without the flaw, so updating PowerStore 500T to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.75% chance of exploitation within 30 days, higher than 55% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update PowerStore 500T to 4.1.0.6-2771237 or later or 4.3.1.2-2771239 or later, whichever matches your release line, or a later version.

Official description
Dell PowerStore contains a Command Injection vulnerability. An authenticated user with limited privileges could potentially exploit this vulnerability to execute arbitrary commands with root privileges.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
