Security readout for executives and security teams
This is a denial-of-service issue in Undertow used by Red Hat WildFly. Persistent HTTP connections can cause Undertow to retain excessive header-cache data, consuming memory until the service becomes unstable or unavailable. Exposure is most likely where Red Hat WildFly using affected Undertow versions accepts persistent HTTP connections from untrusted networks. The bundle identifies WildFly before 11.0.0.Beta1, but version metadata is limited and should be verified against Red Hat advisories. Treat this as a service availability risk. It is not documented here as actively exploited, but internet-facing or business-critical WildFly services should be checked and updated promptly to reduce outage risk. Mitigation focus: Check Red Hat advisories for the applicable fixed package or product update.; Upgrade affected WildFly or Undertow components according to vendor guidance.; Reduce public exposure to affected HTTP services where possible..
