DescriptionCVE.org

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.

AnalysisAI

Missing object-level authorization across three REST API surfaces in DataEase before 2.10.26 enables authenticated platform users to read, modify, and delete resources owned by other users. The affected endpoints cover chart detail retrieval (ChartViewManege), dashboard linkage read and write operations (VisualizationLinkageService), and map geometry management (MapManage) - all of which accepted arbitrary resource identifiers without verifying the requesting user held any permission over the target resource. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated DataEase user session (PR:L per CVSS 4.0 vector); unauthenticated external attackers cannot exploit this directly. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.3 with vector AV:N/AC:L/AT:N/PR:L reflects moderate real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade DataEase to version 2.10.26 or later, which is the vendor-released patch confirmed by the GitHub release at https://github.com/dataease/dataease/releases/tag/v2.10.26 and advisory GHSA-494p-38q6-9gx5. … Detailed patch versions, workarounds, and compensating controls in full report.
