AI Analysis
Technical Summary
CVE-2026-75854 is a missing authentication vulnerability in the Redis wire-protocol plugin of ArcadeDB versions before 26.8.1. The vulnerability permits unauthenticated remote attackers to connect to the Redis port and execute arbitrary commands against any database on the server, including reading, writing, and deleting data, without providing any credentials. This effectively bypasses all security mechanisms intended to protect the database.
Potential Impact
An attacker can fully compromise the integrity and confidentiality of all data stored in the affected ArcadeDB instances by executing arbitrary commands without authentication. This can lead to unauthorized data access, modification, or deletion, severely impacting the availability and trustworthiness of the database.
Mitigation Recommendations
A fix is available in ArcadeDB version 26.8.1. Users should upgrade to version 26.8.1 or later to remediate this vulnerability. No other mitigation guidance is provided or necessary once the patch is applied.
