JDBC URL Validation Bypass in DataEase Leads to RCE

Publication date: 2026-07-07

Last updated on: 2026-07-07

Assigner: GitHub, Inc.

Description

DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, the H2 database JDBC URL validation logic can be bypassed with special Unicode characters whose case-conversion behavior differs between DataEase validation and H2 parsing, allowing attackers to smuggle dangerous parameters such as init in malicious H2 JDBC connection strings and achieve arbitrary code execution. This issue is fixed in version 2.10.24.

Attack-Flow Graph

Mitigation Strategies

The vulnerability is fixed in DataEase version 2.10.24.

To mitigate this vulnerability, you should upgrade your DataEase installation to version 2.10.24 or later.

Executive Summary

This vulnerability exists in DataEase, an open source data visualization and analysis tool, in versions prior to 2.10.24. The issue arises because the H2 database JDBC URL validation logic in DataEase can be bypassed using special Unicode characters. These characters behave differently when case-converted by DataEase's validation compared to how the H2 database parses them. This discrepancy allows attackers to insert dangerous parameters, such as 'init', into malicious H2 JDBC connection strings. Exploiting this flaw can lead to arbitrary code execution on the affected system.

Impact Analysis

The vulnerability can have severe impacts as it allows attackers to execute arbitrary code on systems running vulnerable versions of DataEase. This means an attacker could potentially take control of the affected system, manipulate data, disrupt services, or use the compromised system as a foothold for further attacks.
