CVE-2026-75854 is a critical missing authentication vulnerability in ArcadeDB affecting versions prior to 26.8.1. The flaw resides in the Redis wire-protocol plugin, which accepts connections and processes commands without requiring authentication. An attacker able to reach the Redis service exposed by ArcadeDB can connect without credentials and execute commands against any database hosted on the server, bypassing intended security controls. This permits unauthorized read, write, and delete operations across database contents.
