Unauthenticated data access via missing Redis AUTH
Published Aug 18, 2026 · Updated Aug 18, 2026
Missing authentication in the Redis wire-protocol plugin in ArcadeDB before 26.8.1 allows remote attackers to read, write, and delete data via the Redis port. The plugin accepts Redis client connections and executes commands for any database without requiring an AUTH exchange or binding the session to an authenticated identity. Any network-reachable Redis listener is exposed; no prior account or user interaction is required, and the consequence is direct unauthorized database access rather than code execution.
