CVE-2026-75851: Improper Privilege Management in ArcadeData arcadedb

VulnerabilityCVE-2026-75851cvecve-2026-75851
Published: 08/18/2026 (08/18/2026, 11:19:55 UTC)
Source: CVE Database V5
Vendor/Project: ArcadeData
Product: arcadedb

Description

ArcadeDB server versions 26.7.3 and earlier contain an improper privilege management vulnerability where asynchronous command worker threads do not propagate the authenticated user context. This allows a user with read-only access to execute asynchronous JavaScript commands with unrestricted host access, enabling creation of a server-wide administrator and full privilege escalation. The issue is fixed in version 26.8.1.

Technical Analysis

ArcadeDB server (com.arcadedb:arcadedb-server) versions 26.7.3 and earlier fail to propagate the authenticated principal to asynchronous command worker threads. When an HTTP command is submitted with awaitResponse:false, it executes on an async worker whose DatabaseContext lacks a bound user, causing the scripting authorization gate to be bypassed. This allows a user with read-only access on a single database to submit asynchronous JavaScript commands via the /api/v1/command endpoint to run code with unrestricted host access, such as creating a server-wide administrator user, resulting in full administrative control escalation. The vulnerability is fixed in version 26.8.1.

Potential Impact

An attacker with only read access to a single database can escalate privileges to full administrative control of the ArcadeDB server by exploiting the asynchronous command execution context lacking proper user authorization. This leads to unauthorized creation of administrator accounts and unrestricted host access, severely compromising the server's security.

Mitigation Recommendations

Upgrade ArcadeDB server to version 26.8.1 or later, where this privilege escalation vulnerability is fixed. No other mitigation or temporary workaround is specified. Patch status is confirmed fixed in 26.8.1.
