DataEase is an open source data visualization and analysis tool. Prior to 2.10.26, authenticated users with folder creation permission can store HTML-bearing names through datasource/createFolder or datasetTree/save. The datasource and dataset Move to dialogs in core/core-frontend/src/views/visualized/data/datasource/form/CreatDsGroup.vue and core/core-frontend/src/views/visualized/data/dataset/form/CreatDsGroup.vue read the stored name from a node title attribute and assign search-highlighted content to innerHTML. When another user opens a Move to dialog and types in its search box, attacker-controlled JavaScript can execute in the victim's DataEase session. This issue is fixed in version 2.10.26.
