Overview
The Common Vulnerabilities and Exposures (CVE) system has recently identified a severe vulnerability, known as CVE-2025-49001, in DataEase, an open-source business intelligence and data visualization tool. This vulnerability, due to ineffective secret verification, allows users to forge a JSON Web Token (JWT), potentially leading to unauthorized access or malicious activities. This flaw can impact any organization or individual using versions of DataEase prior to v2.10.10.
The severity of this vulnerability is underscored by its CVSS score of 9.8, indicating a critical threat. The potential for system compromise and data leakage makes it crucial for users to understand this vulnerability and take necessary steps to mitigate its impact.

How the Exploit Works
The exploit takes advantage of a flaw in the secret verification process of DataEase. In versions prior to 2.10.10, the verification process doesn’t work effectively, allowing an attacker to use any secret to forge a JWT token. This token can then be used to gain unauthorized access to the system, potentially compromising sensitive data or disrupting system operations.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited:
POST /token HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"algorithm": "HS256",
"typ": "JWT",
"kid": "anySecret",
"payload": {
"user": "admin"
},
"signature": "..."
}In this example, an attacker sends a POST request to the /token URI with a forged JWT. The system, due to its flawed secret verification process, accepts the ‘anySecret’ value in the ‘kid’ field, and the attacker gains unauthorized access as an admin user.
Mitigation Recommendations
Users are strongly advised to update DataEase to version 2.10.10 or later, where the vulnerability has been fixed. If an immediate update is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these measures only offer temporary protection and cannot completely resolve the vulnerability. Therefore, updating to a patched version remains the most effective solution.
