What is CVE-2026-46457?

An improper input validation issue exists in the NATS component of Apache Camel, affecting versions 4.0.0 to 4.14.7, 4.15.0 to 4.18.2, and 4.19.0 to 4.20.9. This flaw allows clients capable of publishing to specific NATS subjects to inject arbitrary Camel control headers, which can manipulate the behavior of downstream message producers. As these injected headers persist across multiple internal hops, they pose significant risks, enabling potential redirection of HTTP requests, alteration of file names, or overriding of SQL queries. Successful exploitation of this vulnerability can have a severe impact depending on the specific configurations of the downstream producers. It is crucial for users to upgrade to version 4.21.0 or, if on the LTS release streams, to 4.14.8 or 4.18.3 to remediate this issue.

Affected Version(s)

Apache Camel 4.0.0 < 4.14.8

Apache Camel 4.15.0 < 4.18.3

Apache Camel 4.19.0 < 4.21.0
