Upgrade org.apache.camel:camel-atmosphere-websocket to version 4.14.8, 4.18.3, 4.21.0 or higher.
Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the WebsocketConsumer.service process. An attacker can redirect server-side HTTP requests to arbitrary destinations and access sensitive environment variables, application properties, or vault secrets by injecting specially crafted WebSocket query parameters that are mapped into internal headers. This is only exploitable if the WebSocket endpoint is exposed without authentication and is bridged directly into an HTTP producer whose target URI can be influenced from message headers.
Workaround
This vulnerability can be mitigated by stripping Camel control headers from inbound messages before they reach any downstream producer (for example, using removeHeaders('Camel*') and removeHeaders('camel*') at the start of the route), requiring authentication on the WebSocket endpoint, and avoiding bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.
