Route manipulation via unfiltered inbound headers
Published Apr 1, 2025 · Updated Apr 1, 2025
Header injection in Camel-Undertow for Apache Camel 4.8.0 through 4.8.5 and 4.10.0 through 4.10.2 allows remote attackers to alter routes. UndertowHeaderFilterStrategy filters Camel-specific headers only outbound, so inbound HTTP headers enter the Exchange without the intended namespace filter. Exploitation requires an Undertow consumer reachable by remote attackers and a route that passes injected headers to behavior-sensitive components such as camel-bean or camel-exec.

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=4.10.0 <4.10.3
- Affected versionversion=4.8.0 <4.8.6
