CVE-2026-93492: Red Hat Amq Broker 7

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

A flaw was found in Netty's HTTP/2 HpackEncoder. A remote attacker can exploit this by sending HTTP/2 SETTINGS frames with a very large MAX_HEADER_TABLE_SIZE. This causes the HpackEncoder to store an excessive number of unique headers, leading to increased CPU usage and memory consumption, ultimately resulting in a Denial of Service (DoS).
