External risk briefCRITICAL

CVE-2026-44221

Halo Surface Signal

2/ 5

ArcadeDB is a database management system, typically deployed in internal segments or behind application layers. While it includes network-accessible APIs, exposing database administration interfaces directly to the public internet is uncommon and generally considered a misconfiguration. It is primarily a backend data storage service designed to be protected by internal network controls.

Exposure facts

H – Horizon Alert

A security vulnerability exists in ArcadeDB that allows authenticated users to bypass intended authorization controls. Due to a defect in how the system verifies access permissions, an individual with access to one database could read, write, or modify the schema of other databases hosted on the same server. This poses a significant business concern, as it could result in unauthorized data exposure or improper changes to critical information across your database environment.

A – Asset Exposure

This vulnerability impacts the ArcadeDB database management system, which may be deployed in either internal or internet-facing configurations depending on your specific environment. Within an affected system, authenticated users or API tokens could bypass intended security restrictions to modify or extract customer data and database schemas across the entire server. This unauthorized access could allow for the alteration of operational systems or the exposure of sensitive files that should have remained restricted. Please review your database deployments, as this issue affects the integrity and confidentiality of information stored across multiple databases on a single server.

L – Live Threat

The available context does not indicate active exploitation or observed malicious targeting related to this authorization issue. There are currently no reports of public exploit code or proof-of-concept activity, and available threat data suggests the probability of exploitation remains low. Consequently, we have no signals suggesting an immediate, high-likelihood risk of external attack.

O – Operational Fix

To protect your data environment, please ensure your technical teams apply the latest vendor-supplied update for ArcadeDB. This update addresses an authorization flaw that could allow authenticated users to incorrectly access or modify other databases within the same server. Prioritizing this update will ensure that your organization’s record-level and database-level security controls function as intended.
