CVE-2026-93494: Red Hat Build Of Apache Camel For Spring Boot 4

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

A flaw was found in Netty's StompSubframeDecoder component. A remote attacker can exploit this vulnerability by sending a specially crafted STOMP frame body without its terminating null byte. This causes the decoder to allocate a ByteBuf (a buffer for bytes) that is never released, leading to a permanent memory leak. Over time, this uncontrolled memory consumption can result in a Denial of Service (DoS) for the application using the affected STOMP codec.

Affected products
