What is CVE-2026-106139?
CVE-2026-106139 is a medium-severity cross-site scripting vulnerability in Progress Software Kendo UI for Vue, published on 10 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
In Progress® Kendo UI for Vue (@progress/kendo-vue-charts) starting with version 2.5.0 and prior to 16.2.0, the default Chart tooltip renders the formatted point value as raw HTML without encoding, in both the single-point and the shared tooltip. An attacker with low privileges who can influence a string value bound to the chart can supply HTML containing event handlers that execute JavaScript in a user's browser when the user hovers over the affected data point. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application.
