Summary

Progress Kendo UI for Vue (@progress/kendo-vue-charts) from 2.5.0 before 10.1.0 renders the formatted point value of the default Chart tooltip as raw HTML without encoding. Missing output encoding lets injected HTML run script (CWE-80). A remote attacker with low privileges who can influence a string value bound to the chart can run JavaScript in a user's browser when the user hovers over the affected data point.

Description from the CNA

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.
