Horizon Alert
Summary of the vulnerability and why it matters
An issue in ArcadeDB allows authenticated users to bypass security controls and access or modify any database on the server, regardless of their assigned permissions. This could lead to unauthorized data exposure or manipulation.
- Affects multiple databases on a server.
- Compromise requires existing access.
- Can lead to data exposure or modification.
Attack Path
How an attacker could exploit the issue
An attacker with existing database access or API token credentials can leverage this vulnerability to bypass authorization controls. This allows them to read, write, and alter schema across any database on the server, regardless of their initial permissions. Exploitation can occur through specially crafted API requests.
- Authenticated access required.
- Targets database and record authorization.
- Creating new databases disables security.
Live Threat
Current exploitation, exposure, and threat context
This critical vulnerability in ArcadeDB allows authenticated users to bypass record-level and database-level authorization, potentially leading to complete data compromise. While the vulnerability exists, the specific nature of ArcadeDB as a backend database system suggests exploitation is more likely within internal environments rather than widespread public attacks.
- Exploitation requires existing authentication.
- No public exploits are currently known.
- No KEV listing is observed.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Teams should prioritize patching ArcadeDB to version 2.6.4 or later to address the critical authorization bypass vulnerability. If immediate patching is not feasible, implement strict network segmentation and access controls to isolate affected databases and prevent unauthorized access. Continuous monitoring for anomalous database activity and schema changes is crucial.
- Upgrade ArcadeDB to 2.6.4.
- Isolate affected databases.
- Monitor for suspicious schema changes.
