CVE-2026-76224: Improper Control of Generation of Code ('Code Injection') in ArcadeData arcadedb
ArcadeDB before 26.8.1 (arcadedb-gremlin, affected <= 26.7.3) contains a remote code execution vulnerability in its Gremlin query engine. Although the engine defaults to the documented-secure java (gremlin-lang) engine, ArcadeGremlin.executeStatement() silently falls back to the insecure Groovy engine whenever a request carries any query parameter and the query does not parse as gremlin-lang. An authenticated user with any database role, including a read-only reader, can submit a parameterized Gremlin query to trigger the Groovy fallback and execute arbitrary operating system commands as the ArcadeDB server process user.
AI Analysis
Technical Summary
CVE-2026-76224 is a remote code execution vulnerability in ArcadeData's ArcadeDB Gremlin query engine affecting versions prior to 26.8.1 (specifically arcadedb-gremlin <= 26.7.3). The engine defaults to a secure Java-based gremlin-lang engine, but if a query with parameters fails to parse as gremlin-lang, ArcadeGremlin.executeStatement() silently falls back to the insecure Groovy engine. This fallback allows an authenticated user with any database role, including read-only, to submit a parameterized Gremlin query that triggers the Groovy fallback and execute arbitrary operating system commands with the privileges of the ArcadeDB server process.
Potential Impact
An authenticated user with any database role, including read-only, can execute arbitrary operating system commands on the server running ArcadeDB. This can lead to full compromise of the server environment under the ArcadeDB process user context. The vulnerability does not require elevated privileges beyond authentication and affects the server's integrity and confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to authenticated users and monitor for suspicious query patterns that could trigger the Groovy fallback. Avoid using parameterized queries that do not parse as gremlin-lang or disable the Groovy fallback if possible.
