Argument injection and path traversal via custom flags
Published Jul 6, 2026 · Updated Jul 6, 2026
Argument injection in Apache Camel Docling 4.15.0 through 4.18.2 allows attackers to pass unintended flags to the docling subprocess. DoclingProducer appends CamelDoclingCustomArguments header values to a ProcessBuilder argument list after only denylist checks and a literal ../ path test. Exposure requires a route to place externally influenced values in custom-argument or path-bearing headers; shell metacharacters do not yield OS command execution.

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=4.15.0 <4.18.3
