CVE-2026-46726
Description
A flaw was found in the Apache Camel Vertx Websocket component. This vulnerability allows an unauthenticated remote attacker to inject malicious query parameters into a WebSocket connection. This can lead to Server-Side Request Forgery (SSRF), where the server is coerced into making requests to arbitrary internal or external destinations. Additionally, the flaw can result in the disclosure of sensitive information, including environment variables, application properties, and vault secrets.
Statement
A flaw was found in the Apache Camel Vertx-WebSocket component. The WebSocket consumer copies inbound query and path parameters into the Camel Exchange header map without applying a HeaderFilterStrategy. An attacker can inject Camel-internal control headers (such as CamelHttpUri) via WebSocket query parameters, causing SSRF when routed to an HTTP producer. The HTTP producer also resolves Camel property placeholders on the attacker-controlled URI, leaking environment variables, application properties, and vault secrets. Red Hat builds of Apache Camel for Spring Boot and Quarkus ship the affected camel-vertx-websocket component.
Mitigation
Restrict access to exposed WebSocket endpoints with authentication. If unable to upgrade, strip Camel-internal headers from inbound WebSocket messages before they reach downstream producers (for example removeHeaders('Camel*') and removeHeaders('camel*') at the start of the route).
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
