AI Analysis

Impact

ArcadeDB versions 26.2.1 through 26.10.1 contain a missing authorization flaw in the Bolt protocol handler. Authenticated users can run the SHOW DATABASES command, which enumerates all database names. This leaks tenant or project identifiers, potentially exposing sensitive project structure and aiding further attacks.

Affected Systems

All ArcadeDB installations from version 26.2.1 up to but excluding 26.10.1, published by ArcadeData.

Risk and Exploitability

The flaw has a CVSS score of 5.3 and an EPSS score of less than 1 %, indicating a modest risk profile. Attackers must first obtain valid credentials for any database but can then issue a single Bolt‑protocol query to gather information. The vulnerability is not listed in the CISA KEV catalog, suggesting no currently documented widespread exploitation. The primary impact is confidentiality degradation through the disclosure of database names.
