StorageGRID: Server-Side Request Forgery
CVE-2025-26515 is a high-severity server-side request forgery vulnerability in StorageGRID from NetApp, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 11.8.0.15, 11.9.0.8 as the first without the flaw, so updating StorageGRID to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.34% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update StorageGRID to 11.8.0.15 or 11.9.0.8, whichever matches your release line, or a later version.
- Read the advisory on security.netapp.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| NetApp | StorageGRID | before 11.8.0.15; before 11.9.0.8 | 11.8.0.15, 11.9.0.8 |

Official description
StorageGRID (formerly StorageGRID Webscale) versions prior to 11.8.0.15 and 11.9.0.8 without Single Sign-on enabled are susceptible to a Server-Side Request Forgery (SSRF) vulnerability. Successful exploit could allow an unauthenticated attacker to change the password of any Grid Manager or Tenant Manager non-federated user.

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.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
