CVE-2026-93574: Red Hat Amq Broker 7

Medium severity, CVSS 6.5. EPSS: 1.4% chance of exploitation in the next 30 days.

A flaw was found in Netty's `netty-codec-http` component. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an attacker to bypass security controls or access unauthorized resources in proxy/backend deployments.
