What is CVE-2026-102756?
CVE-2026-102756 is a medium-severity cross-site scripting vulnerability in dataease, published on 14 Oct 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
DataEase is an open source data visualization and analysis tool. Prior to 2.10.26, authenticated users who can edit dataset fields and chart configuration can store an HTML-bearing dimension value in a bar-horizontal chart. When lengthLimit truncates the category axis label, configAxisLabelLengthLimit in core/core-frontend/src/views/chart/components/js/panel/common/common_antv.ts retrieves the full label and assigns it to the g2-tooltip-title element through innerHTML. A victim who opens the dashboard and hovers the truncated label can execute attacker-controlled JavaScript in the victim's DataEase session. This issue is fixed in version 2.10.26.
