CVE-2026-53729 in DataEase
Summary
by MITRE • 07/07/2026
DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, any authenticated user can download (/exportCenter/download/{id}), delete (/exportCenter/delete), retry (/exportCenter/retry/{id}), or generate download links (/exportCenter/generateDownloadUri/{id}) for export tasks belonging to other users by manipulating the task ID parameter, and the /exportCenter/download/{id} endpoint is whitelisted from authentication, allowing unauthenticated access to exported files. This issue is fixed in version 2.10.24.

This vulnerability represents a critical authorization bypass flaw in DataEase versions prior to 2.10.24 that enables authenticated users to perform unauthorized operations on export tasks belonging to other users. The core technical issue stems from inadequate input validation and access control enforcement within the export center functionality, specifically around the task ID parameter manipulation. Attackers can exploit this weakness by simply modifying the numeric identifier in API endpoints such as /exportCenter/download/{id}, /exportCenter/delete/{id}, /exportCenter/retry/{id}, and /exportCenter/generateDownloadUri/{id} to access or manipulate files created by different users within the system.
The vulnerability manifests through a lack of proper user context validation during export operations, allowing privilege escalation from regular user level to unauthorized administrative-like capabilities. The system fails to verify that the requesting user has legitimate authorization to access specific export tasks based on ownership relationships. This flaw directly maps to CWE-285: Improper Authorization, which is classified under the OWASP Top Ten as an authentication and access control weakness. The issue is further compounded by the fact that the download endpoint specifically lacks authentication requirements, creating a path for unauthenticated access to sensitive data that was previously protected through proper authorization mechanisms.
The operational impact of this vulnerability extends beyond simple data exposure to include potential data manipulation and service disruption. An attacker with valid credentials could systematically enumerate export task IDs to discover and access files belonging to other users, potentially including sensitive business intelligence reports, financial data, or personal information. The ability to delete or retry export tasks also provides opportunities for denial of service attacks against legitimate users. This represents a significant breach in the principle of least privilege and could enable attackers to gain insights into organizational data structures and user activities through systematic exploration of exported content.
Mitigation strategies should focus on implementing robust access control checks that validate user ownership before executing any operations on export tasks. The system must enforce proper authorization boundaries at each endpoint, ensuring that users can only perform actions on resources they own or have explicit permission to access. Input validation should be strengthened to prevent parameter manipulation attacks, and the authentication requirements for download endpoints should be properly enforced to prevent unauthorized file access. Organizations should also implement audit logging for export operations to detect suspicious activities and establish proper user role management to limit access to sensitive data processing functions.
The vulnerability aligns with several ATT&CK techniques including T1078: Valid Accounts and T1566: Phishing, as it exploits legitimate user credentials to gain unauthorized access. It also demonstrates the importance of defense in depth principles where multiple layers of security controls should be implemented to prevent a single point of failure. The fix in version 2.10.24 likely includes proper access control validation, input sanitization, and authentication enforcement mechanisms that align with secure coding practices as recommended by NIST SP 800-53 and ISO/IEC 27001 standards for information security management.
