redhat camel-spring-boot CVE-2026-81624 vulnerability in Red Hat Products
Published on August 31, 2026

Undertow-core: undertow: websocketcontainer defaults for buffers and timeouts are infinite
Undertow is a flexible performant web server used in JBoss EAP and WildFly. A flaw was found in how Undertow handles WebSocket connections. Specifically, certain configuration limits like message buffer sizes and session timeouts cannot be adjusted and default to being unlimited. This allows a remote attacker to send large amounts of data or maintain connections indefinitely, potentially crashing the server by exhausting its memory or other resources.
