CVE-2026-82878 in DataEase
Summary
by MITRE • 08/31/2026
DataEase versions before 2.10.26 omit object-level authorization checks on geographic information, dashboard linkage, and chart detail REST endpoints, allowing authenticated users to access resources belonging to other users. Attackers can overwrite or delete map geometry, modify dashboard linkages, and retrieve chart metadata and configuration for resources they do not own by supplying arbitrary identifiers in requests.

DataEase versions prior to 2.10.26 contain a critical authorization flaw within its REST API implementation that allows authenticated users to bypass object-level access controls. This vulnerability stems from the application's failure to validate whether the requesting user possesses ownership or appropriate permissions for specific geographic information, dashboard linkage configurations, and chart detail resources before processing requests targeting those entities. By omitting these essential checks, the system inadvertently exposes sensitive internal data structures and configuration details to any valid account holder on the platform, regardless of their actual role or assigned workspace memberships.
The technical mechanism behind this exploitation involves supplying arbitrary identifiers in HTTP requests directed at specific endpoints responsible for managing map geometries, dashboard associations, and chart metadata. Since the backend logic does not cross-reference these provided identifiers against an access control list tied to the authenticated session's user identity, it processes operations on resources belonging to other users or organizations within the same instance. This lack of direct object reference validation enables attackers to perform unauthorized read, write, and delete actions on data they do not own, effectively bypassing the intended multi-tenant isolation boundaries established by the application architecture.
The operational impact of this vulnerability is significant for environments relying on DataEase for business intelligence and reporting. Attackers can retrieve sensitive chart metadata and configuration details, which may reveal underlying database queries, connection strings, or proprietary analytical models belonging to competitors or internal departments. Furthermore, the ability to overwrite map geometry data allows an attacker to distort visual representations of critical geographic datasets, potentially leading to misinformed decision-making if such tampered visuals are consumed by other stakeholders. The capability to modify dashboard linkages can disrupt user workflows and break existing reporting structures, while the potential for deletion poses a risk of permanent data loss or service disruption for affected users.
This flaw aligns with CWE-284 Improper Access Control, specifically reflecting issues related to insufficient authorization checks on sensitive objects. In terms of offensive security frameworks, this vulnerability facilitates lateral movement and privilege escalation within the application layer by allowing an attacker to manipulate resources across different user contexts without needing elevated privileges initially. It also relates to CWE-601 URL Redirection to Untrusted Site or Domain if such linkages are exploited for phishing, though primarily it represents a fundamental failure in enforcing data isolation policies.
To mitigate this risk, organizations running DataEase must immediately upgrade to version 2.10.26 or later where these authorization checks have been implemented and validated by the development team. For environments that cannot be patched instantly due to operational constraints, implementing a Web Application Firewall rule set can help detect anomalous patterns of identifier manipulation in API requests targeting geographic and dashboard endpoints. Additionally, reviewing audit logs for unusual access patterns to resources outside expected user boundaries may aid in identifying ongoing exploitation attempts while permanent remediation is prepared.
