CVE-2026-87670

Quick assessment

Affected
Brocade Fabric OS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Brocade Fabric OS 10.0.1 版本之前的 REST API 网关中存在一个授权逻辑漏洞。该漏洞使得内部网关对受限管理端点的保护完全依赖于客户端控制的 HTTP 头。任何具有有效 REST 会话的经过身份验证的用户都可以通过伪造这些 HTTP 头，从而未经授权地访问内部管理端点。这使低权限用户能够查看敏感的设备元数据、硬件内存巡视状态以及固件完整性审计日志。

Source: CVE Program / CVE List V5
Vulnerability Description
An authorization logic vulnerability exists in the Brocade Fabric OS versions before 10.0.1 REST API gateway. The internal gate guarding restricted management endpoints relies exclusively on client-controlled HTTP headers. An authenticated user with any valid REST session can spoof these headers to gain unauthorized access to internal management endpoints. This allows low-privilege users to view sensitive chassis metadata, hardware memory patrolling state, and firmware integrity audit logs.
