CVE-2026-76224 ArcadeData CVE debrief

Who should care

Defenders and administrators of systems using ArcadeDB, especially those with versions less than 26.8.1, should assess exposure and apply patches or updates to prevent exploitation. Database administrators, security teams, and IT personnel responsible for maintaining and securing databases should prioritize verifying and mitigating this vulnerability.

Why it matters

CVE-2026-76224 is a remote code execution vulnerability in ArcadeDB's Gremlin query engine. Defenders should prioritize verifying exposure and applying patches due to the potential for unauthorized access and arbitrary command execution. The vulnerability requires verification from official sources, and its impact on database confidentiality, integrity, and availability needs assessment.

• Potential remote code execution as the ArcadeDB server process user.
• Possible unauthorized access and arbitrary operating system command execution.
• Required verification of exposure and patch application due to limited corpus information.
• Potential impact on database confidentiality, integrity, and availability.

Technical summary

The ArcadeDB Gremlin query engine has a remote code execution vulnerability due to a fallback to the insecure Groovy engine when a request carries query parameters and the query does not parse as gremlin-lang. An authenticated user with any database role can submit a parameterized Gremlin query to trigger the Groovy fallback and execute arbitrary operating system commands as the ArcadeDB server process user. This issue requires verification of exposure and patch application due to its potential impact on database confidentiality, integrity, and availability.

Defensive priority

Defenders should prioritize verifying exposure and applying patches due to the remote code execution vulnerability in ArcadeDB's Gremlin query engine.

Recommended defensive actions

• Verify if the system uses ArcadeDB with a version less than 26.8.1 and assess exposure.
• Apply patches or updates to ArcadeDB to prevent exploitation.
• Monitor and restrict access to the Gremlin query engine.
• Review and limit database roles and permissions to prevent unauthorized access.
• Track exceptions and retest remediated assets.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Evidence notes

The CVE record and NVD entry provide details on the remote code execution vulnerability in ArcadeDB's Gremlin query engine. However, the corpus does not establish versions beyond 26.7.3 and 26.8.1, exploitation, or specific impact, requiring verification from official sources.
