Executive brief
DataEase is an open-source business intelligence and data visualization tool. Versions before 2.10.26 lack proper permission checks on REST endpoints for maps, dashboards, and charts, allowing authenticated users to access, modify, or delete data they should not have permission to view. An attacker could manipulate map geometry, change dashboard linkages, or exfiltrate chart configurations belonging to other users within the same system.
Technical details
The vulnerability is a missing object-level authorization check (CWE-639) in DataEase REST endpoints responsible for geographic information, dashboard linkage, and chart detail operations. Authenticated users can access resources by supplying arbitrary object identifiers in requests, bypassing authorization validation. The attack requires valid authentication credentials but no special privileges or user interaction. Attackers can read, modify, or delete map geometry and chart metadata, and reconfigure dashboard linkages for any resource in the system. The fix was merged on 2026-07-25 and is available in version 2.10.26 and later, as confirmed by GitHub commit 5fe46c4 which adds business-level permission checks (BusiPerCheckDTO).
