"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.");
