What an attacker can do

A user with only read access to a single database can submit an asynchronous JavaScript (language=js) command via the /api/v1/command endpoint to run code with unrestricted host access (e.g., database.getSecurity().createUser) and create a server-wide administrator, escalating to full administrative control. Vendor/CNA’s CVSS 4.0 assessment (base score 9.4/10) rates confidentiality, integrity and availability impact as high.
