Why it matters

CVE-2026-94575 is a logic vulnerability in Brocade Fabric OS that allows authenticated users to bypass RBAC checks, potentially leading to unauthorized access to restricted configuration settings. Defenders should prioritize verification, remediation, and restricted access to sensitive settings.

• Verification of Fabric OS version and configuration is required to determine exposure.
• Restricting access to sensitive configuration settings can help mitigate potential impact.
• Upgrading to Fabric OS version 10.0.1 or later can prevent exploitation.

Technical summary

The vulnerability allows an authenticated, low-privileged user to bypass inner Role-Based Access Control (RBAC) checks under specific environmental conditions, lowering the system authorization mode for the active session context. This allows access to restricted configuration settings intended exclusively for administrative roles. The vulnerability impacts Brocade Fabric OS systems, requiring verification of version and configuration to determine exposure. Successful exploitation requires specific environmental conditions to be met.

Defensive priority

Defenders should prioritize verifying and upgrading to Fabric OS version 10.0.1 or later, and restrict access to sensitive configuration settings.

Recommended defensive actions

• Verify and upgrade to Fabric OS version 10.0.1 or later
• Restrict access to sensitive configuration settings
• Monitor system authorization modes and session contexts
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
