StorageGRID (formerly StorageGRID Webscale): Authentication Bypass Using an Alternate Path or Channel

Published Updated By the CyberSecBulletin desk

CVE-2026-22058 is a critical-severity authentication bypass using an alternate path or channel vulnerability in StorageGRID (formerly StorageGRID Webscale) from NetApp, with a CVSS 4.0 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 11.9.0.15, 12.0.0.9, 12.1.0.1 as the first without the flaw, so updating StorageGRID (formerly StorageGRID Webscale) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update StorageGRID (formerly StorageGRID Webscale) to 11.9.0.15, 12.0.0.9, 12.1.0.1 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

StorageGRID (formerly StorageGRID Webscale) versions 11.3 and higher allow an attacker with product-specific knowledge and the ability to communicate with the Grid Network on certain ports to make unauthorized requests.

The underlying weakness: Authentication Bypass Using an Alternate Path or Channel

The product requires authentication, but the product has an alternate path or channel that does not require authentication.

How developers prevent this class of flaw

  • Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
