CVE-2026-87663
An authentication bypass and command injection vulnerability exists in the inter-switch remote execution service of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When processing remote command execution IPC frames across the fabric, the receiving switch processes these commands at an elevated processing level without proper verification of transmitted parameters. This allows an attacker on a single fabric-connected switch to escalate privileges and execute arbitrary root commands locally or across other managed fabric members where remote execution functionality is enabled.
