ArcadeDB versions before 26.8.1 fail to sanitize database names in the POST /api/v1/server endpoint's create database and drop database commands, allowing authenticated root users to write and delete arbitrary files outside the configured database directory. Attackers can supply database names containing ../ sequences to create databases at arbitrary filesystem paths or recursively delete directories the server process can access.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
