PowerStore 500T: Server-Side Request Forgery
CVE-2026-116411 is a high-severity server-side request forgery vulnerability in PowerStore 500T 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 version 5.1.0.0-2798105 or later as the first without the flaw, so updating PowerStore 500T to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.42% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
Dell PowerStore contains a Server-Side Request Forgery (SSRF) vulnerability. An authenticated user with limited privileges could potentially exploit this vulnerability, potentially leading to information disclosure via requests to internal services.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Server-Side Request Forgery
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
How developers prevent this class of flaw
- If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
- If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.

- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
