CVE-2026-55993
Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Atmosphere Websocket Component. The camel-atmosphere-websocket consumer mapped inbound WebSocket query parameters into the Camel Exchange header map without applying any HeaderFilterStrategy (WebsocketConsumer.sendEventNotification() iterates the query-string map collected in WebsocketConsumer.service() and copies each entry into the Exchange). Because nothing blocked the Camel header namespace, a client connecting to the WebSocket endpoint could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as query parameters. In a route where the WebSocket consumer feeds a downstream HTTP producer, the injected CamelHttpUri redirects the server-side HTTP request to an attacker-chosen destination (server-side request forgery - for example to an internal service or a cloud metadata endpoint). In addition, the HTTP producer resolves Camel property placeholders on the resulting (attacker-controlled) URI, so placeholders embedded in the injected value - such as an environment-variable ref
