CVE-2026-75854 · Severity: critical · CVSS 9.8 · Published 2026-08-18

ArcadeDB's optional Redis compatibility plugin allows external tools and scripts to interact with databases using the standard Redis protocol. The plugin has no authentication checks, enabling any attacker with network access to the Redis port to read, modify, and delete data across all databases without providing any credentials—effectively granting complete database control to the internet if the feature is enabled.

## Technical details

The vulnerability is a missing authentication check (CWE-306) in the RedisNetworkExecutor component of ArcadeDB's Redis wire-protocol plugin. Unlike ArcadeDB's other protocol emulators (Postgres, MongoDB), the Redis handler accepts raw TCP connections on the configured Redis port (default 6379, bound to 0.0.0.0 by default) and processes RESP protocol commands (GET, SET, HSET, HGET, HMGET, HDEL, etc.) without ever calling authentication APIs or validating user credentials. Attackers with network access can connect using any standard Redis client (redis-cli, Jedis) and immediately execute arbitrary read, write, and delete operations against all databases on the server. The fix is available in version 26.8.1 and later, where authentication has been implemented.
