Description

The BPMN System REST APIs do not sufficiently validate input parameters, allowing authenticated users to submit crafted requests that can lead to the execution of arbitrary commands on the server.

An authenticated user can leverage this vulnerability to execute arbitrary commands with the privileges of the product's runtime account. The scope of potential damage is contingent upon the permissions assigned to this account.
