Last modified

CVE-2026-75855 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
