Scores, vectors, weaknesses and fixed releases are quoted from vendor advisories that cover only CVE-2026-40047; bulletin-wide values are not repeated here.

Is CVE-2026-40047 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-40047 is not in the CISA KEV catalog (checked ) and no tracked advisory for it reports exploitation. That is not proof the vulnerability cannot be exploited.

How do I fix CVE-2026-40047?

Upgrade to a fixed release named by the vendor:

  • Apache: 4.18.3
  • Red Hat: 4.18, 4.18.3
  • For deployments that cannot upgrade immediately, strip the CamelDoclingCustomArguments header from inbound HTTP messages before the docling producer (for example removeHeaders('CamelDocling*') at the start of the route). Additionally, restrict HTTP endpoint access with authentication. (Red Hat)

    Critical [CVE-2026-40047] Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in Apache Camel Docling component

    CVE-2026-40047Source published Source updated

    Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in Apache Camel Docling component. The camel-docling component invokes the external `docling` command-line tool by assembling an argument list in DoclingProducer and executing it through java.lang.ProcessBuilder. Custom CLI arguments supplied through the `CamelDoclingCustomArguments` exchange header (a List ) were appended to that argument list with insufficient validation: the original implementation relied on a denylist of disallowed flags and only rejected path values that contained a literal `../` sequence. As a result, a Camel route that forwards externally-influenced data into the `CamelDoclingCustomArguments` header (or into the path-bearing headers used to build the invocation) could…
