Summary

Progress Software's Kendo UI for jQuery is affected: its Chart shared tooltip treats bound category and series-name values as raw HTML. An attacker who can influence the data a chart uses can reach this remotely, without logging in, by getting a user to display the shared tooltip, and the injected script then runs in that user's browser with limited access to confidentiality and integrity.

Read the original description

In Progress Kendo UI for jQuery, Chart shared-tooltip rendering treats bound category and series-name values as raw HTML. An attacker who can influence values consumed by an affected Chart can inject markup that executes as JavaScript when a user displays the shared tooltip. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. Version 2016.2.607 or earlier may be affected, but earlier releases have not been verified. The latest vulnerable version is 2026.3.1015; the issue is fixed in version 2026.4.1111.

Who should check

CISA KEV: CVE-2026-124697 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-124697 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/kb-security-kendo-chart-shared-tooltip-xss-cve-2026-124697
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
