• Compromise of confidentiality and integrity of accessible data
• Need for verification of affected versions and exposure
• Priority for applying vendor-provided patch or workarounds

Technical summary

The vulnerability exists in the TabStrip, Menu, and PanelBar components of Kendo UI for jQuery.
