CVE-2026-75840: Comparison Using Wrong Factors in ArcadeData arcadedb
ArcadeDB versions prior to 26.8.1 contain a high-severity arbitrary file read vulnerability in the GraalVM JavaScript sandbox allowlist enforcement. The vulnerability arises because unescaped regular expressions are used to validate package names, allowing attackers with trigger creation privileges to exploit Java.type() to access Java classes that can read arbitrary files on the host system.
AI Analysis
Technical Summary
CVE-2026-75840 affects ArcadeDB before version 26.8.1. The vulnerability is due to improper validation in the GraalVM JavaScript sandbox allowlist enforcement, which uses unescaped regular expressions for package name validation. This flaw allows an attacker with trigger creation privileges to invoke Java.type() to access java.util.zip.ZipFile or java.util.jar.JarFile classes, enabling arbitrary file reads on the server hosting ArcadeDB.
Potential Impact
An attacker with the ability to create triggers in ArcadeDB can exploit this vulnerability to read arbitrary files on the host system with the privileges of the ArcadeDB server process. This can lead to unauthorized disclosure of sensitive information stored on the server.
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 additional mitigation guidance is provided in the vendor advisory.
