CVE-2026-87678

An input validation and output encoding vulnerability exists in the web management interface of Brocade Fabric OS versions before 10.0.1. When configuring Federated Authentication (FA), the system fails to sanitize the Identity Provider (IdP) issuer parameter. An authenticated administrator—or an attacker capable of supplying crafted FA configuration files during an import routine—can inject arbitrary web server directives. This can lead to service denial by preventing the web management daemon from starting, or potentially alter web server security controls.
