Workarounds
CNA: Option 1 — Server-wide configuration to disable websockets handshake: <!-- Remove <websockets/> from standalone.xml servlet-container --> <servlet-container name="default"> <jsp-config/> <!-- <websockets/> ← remove this line entirely --> </servlet-container> isWebsocketsEnabled() returns false → no WebSocket upgrade accepted for any deployment. Option 2 — Per-application configuration to disable websockets handshake: <!-- WEB-INF/jboss-web.xml inside the WAR --> <jboss-web> <enable-websockets>false</enable-websockets> </jboss-web> Only that specific WAR's @ServerEndpoint classes are not registered.
There are currently no legacy QID mappings associated with this CVE.
