Vulnerability details
The vulnerability allows a remote attacker to inject unintended command-line arguments and perform path traversal.
The vulnerability exists due to improper neutralization of argument delimiters in a command and insufficient path validation in DoclingProducer when processing externally influenced custom CLI arguments and path-bearing headers. A remote attacker can supply crafted header values to inject unintended arguments and perform path traversal.
The issue applies when a Camel route forwards externally influenced data into the CamelDoclingCustomArguments header or path-bearing headers used to build the docling invocation.
