- Severity: CVSS 4.7 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2026.3.1015
- Published: 2026-10-15 · Updated: 2026-10-15

## Affected

- Progress Software Kendo UI for jQuery: from 2019.2.514, fixed in 2026.3.1015

## Description

In Progress® Kendo® UI for jQuery versions starting with 2019.2.514 and prior to 2026.3.1015, the PanelBar component inserts data source item URL values into a single-quoted href attribute without proper encoding. An attacker who can control an item URL can inject additional HTML attributes, including event handlers, and execute JavaScript in a user's browser when the affected item is interacted with. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.
