CVE-2026-71467

HIGH CVSS 3.1: 7.5
Updated Aug 12, 2026
Red Hat
Parameter Value
CVSS 7.5 (HIGH)
Type CWE-287 (Improper Authentication)
Vendor Red Hat
Public PoC No

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.
