Summary
Kendo UI for jQuery from Progress Software has a cross-site scripting flaw in the Form item hint option, which is rendered as HTML instead of plain text. An attacker can reach it remotely, without logging in, by influencing a form item's hint, but a user must view the rendered form for the attacker's script to run in their browser.
Read the original description
In Progress Kendo UI for jQuery Form, the items[].hint option is documented as a string but is rendered as HTML. An attacker who can influence a Form item's hint can cause attacker-controlled markup to execute as JavaScript when a user views the rendered form. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The first affected version is 2020.2.513; the latest vulnerable version is 2026.3.1015. The issue is fixed in version 2026.4.1111.
Who should check
Teams shipping Kendo UI for jQuery Form that let an attacker influence Form item hint values; upgrade to 2026.4.1111 or later.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-124695 (Cross-Site Scripting in Kendo UI for jQuery Form Item Hints), using the cve.now data below.
Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

Affected:
- Progress Software Kendo UI for jQuery: from 2020.2.513, through 2026.3.1015
Fixed versions: 2026.4.1111.
Conditions (all must be true for the bug to be hit):
- Application uses an affected version and allows an attacker to control Form item items[].hint values. (source: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/kb-security-kendo-form-item-hint-xss-cve-2026-124695)

CISA KEV: CVE-2026-124695 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-124695 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-form-item-hint-xss-cve-2026-124695
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.
