CVE-2026-76224: Improper Control of Generation of Code ('Code Injection') in ArcadeData arcadedb
Description
ArcadeDB versions before 26.8.1 contain a remote code execution vulnerability in the Gremlin query engine. The vulnerability arises because the ArcadeGremlin.executeStatement() method falls back to an insecure Groovy engine when a query with parameters does not parse as gremlin-lang. This fallback allows an authenticated user with any database role, including read-only, to execute arbitrary operating system commands as the server process user.

Technical Analysis
CVE-2026-76224 is a remote code execution vulnerability in ArcadeDB's Gremlin query engine affecting versions prior to 26.8.1. The engine defaults to a secure Java-based gremlin-lang, but when a query with parameters fails to parse as gremlin-lang, the system silently falls back to an insecure Groovy engine. This fallback can be triggered by any authenticated user, even those with read-only roles, allowing them to execute arbitrary OS commands with the privileges of the ArcadeDB server process.
Potential Impact
An attacker with any authenticated database role can execute arbitrary operating system commands on the server hosting ArcadeDB. This can lead to full compromise of the server environment, data theft, data manipulation, or service disruption. The vulnerability is high severity with a CVSS 4.0 score of 8.7, indicating critical impact on confidentiality, integrity, and availability.
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 vendor advisory content was provided, but the version information indicates an official fix exists. Until upgraded, restrict access to authenticated users and monitor for suspicious query activity.
