SSRF and secret disclosure via injected control headers
Published Jul 6, 2026 · Updated Jul 6, 2026
SSRF in Apache Camel Atmosphere Websocket allows remote attackers to redirect downstream HTTP requests through injected control headers. WebsocketConsumer.sendEventNotification copies connection query parameters into Exchange headers without applying the inherited HeaderFilterStrategy, so CamelHttpUri overrides the HTTP producer target and property placeholders resolve before transmission. Reachability requires an affected consumer route feeding an HTTP producer and a transport that populates the query map; an unauthenticated endpoint then exposes internal requests and resolved environment, application, or vault secrets.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=4.0.0 <4.14.8
- Affected versionversion=4.15.0 <4.18.3
- Affected versionversion=4.19.0 <4.21.0
