CVE-2026-71467— Acm-search-v2-api-rhel9: search-v2-api: authentication bypass on /federated via upgrade: websocket header spoofing

Quick assessment

Affected
Red Hat Red Hat Advanced Cluster Management for Kubernetes 2.17
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.

Redhat Advanced Cluster Management是美国Redhat公司的一款集中式的 Kubernetes 集群管理平台。 Redhat Advanced Cluster Management存在授权问题漏洞，该漏洞源于认证中间件在请求包含Upgrade: websocket头时无条件跳过认证，可能导致未经身份验证的攻击者通过发送特制HTTP POST请求到/federated端点绕过认证，访问所有配置的远程管理中心的联合搜索结果，导致信息泄露。

Vulnerability Title
Acm-search-v2-api-rhel9: search-v2-api: authentication bypass on /federated via upgrade: websocket header spoofing
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in search-v2-api. The authentication middleware in the affected component unconditionally skips authentication when a request includes an `Upgrade: websocket` header. An unauthenticated attacker can exploit this by sending a specially crafted HTTP POST request to the `/federated` endpoint with the `Upgrade: websocket` header. This allows the attacker to bypass authentication and access federated search results across all configured remote managed hubs, leading to information disclosure.
