Kendo UI for jQuery: Cross-site scripting in PivotGrid axis chips
Summary
Kendo UI for jQuery versions 2026.3.1015 up to, but not including, 2026.4.1110 do not encode axis field names in the PivotGrid and PivotConfigurator chip template. An attacker who can influence an axis field name can run JavaScript in the browser of a user who views the rendered chip. A user must view the affected view, and the script can access data in the user's browser context, which may affect confidentiality and integrity. The CVSS score is 7.1 (High).
Affected
- Kendo UI for jQuery 2026.3.1015 up to, but not including, 2026.4.1110
- Earlier versions: Unknown. The first affected release has not been established.
Fixed in

Exploitation
- Not known to be exploited in the wild (as of 11 Nov 2026)
- No public exploit code indexed (as of 11 Nov 2026)
- CISA KEV status: not checked
Our recommendation
- Inventory all applications that use Kendo UI for jQuery, including internal and vendor-supplied products
- Upgrade to 2026.4.1110 or later
- Until patched, restrict who can supply pivot or axis field names and review untrusted data sources such as imported CSV or Excel files
- Check the Telerik KB and NVD for updates and review CISA KEV once NVD analysis is complete

Original description (NVD)
In Progress Kendo UI for jQuery versions 2026.3.1015 up to, but not including, 2026.4.1110, PivotGrid and PivotConfigurator axis field names are passed to a chip template without appropriate encoding. An attacker who can influence an axis field name can cause JavaScript to execute when a user views the rendered chip. The field name can be interpreted as HTML in both attribute and element contexts. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The first affected release has not been established.
