Apache Camel 4.14.x < 4.14.6 / 4.15.x < 4.18.1 RCE (CVE-2026-33453)

high Nessus Plugin ID 322982

Language:

Synopsis

The remote host contains an integration framework that is affected by a remote code execution vulnerability.

Description

The version of Apache Camel on the remote host is 4.14.x prior to 4.14.6 or 4.15.x through 4.18.x prior to 4.18.1. It is, therefore, affected by a remote code execution vulnerability:

- The camel-coap component maps incoming CoAP request URI query parameters directly into Camel Exchange In message headers without applying any HeaderFilterStrategy. An unauthenticated attacker who can send a CoAP UDP packet to a Camel route can inject arbitrary Camel internal headers into the Exchange. When the route delivers the message to a header-sensitive producer such as camel-exec, the injected headers can override the executable and arguments, resulting in arbitrary OS command execution. (CVE-2026-33453)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Camel version 4.14.6, 4.18.1, or later.
