CVE-2026-106162 (GCVE-0-2026-106162)

Vulnerability from cvelistv5 – Published: 2026-10-15 13:20 – Updated: 2026-10-15 18:30

Title
Cross-Site Scripting in FileManager Drag Hints in Kendo UI for jQuery
Summary
In Progress® Kendo® UI for jQuery versions starting with 2023.3.1010 and prior to 2026.3.1015, the FileManager component renders remotely supplied item names as HTML in its default drag hint even though the corresponding list items are encoded. An attacker who can control an item name can inject HTML containing event handlers that execute JavaScript in a user's browser when the user drags the affected item. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.

Title
Cross-Site Scripting via Badge Text Binding in Kendo UI for jQuery
Summary
In Progress® Kendo® UI for jQuery releases starting with v2020.1.114 and prior to 2026.3.1015, the Badge text method renders string values as raw HTML without encoding, including values supplied through text binding. An attacker who can modify data bound to a Badge can supply HTML containing event handlers that execute JavaScript in a user's browser when the Badge renders the value. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.

Title
Cross-Site Scripting via Scheduler Resource Colors in Kendo UI for jQuery
Summary
In Progress® Kendo® UI for jQuery, in v2026.3.811 and earlier, the Scheduler Day, Timeline, Month, and Agenda views insert resource color values into quoted event wrapper attributes without proper encoding. An attacker who can control a resource color can inject additional HTML attributes, including event handlers, and execute JavaScript in a user's browser when the affected event is interacted with. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. The earliest affected version has not been confirmed. This issue is fixed in version 2026.3.1015.

Title
Cross-Site Scripting in Validator Validation Messages in Kendo UI for jQuery
Summary
In Progress® Kendo® UI for jQuery versions starting with 2012.2.710 and prior to 2026.3.1015, the Validator decodes validation messages from data-msg-* attributes and parses the resulting text as HTML. An attacker who can modify a validation message can cause HTML that was correctly escaped in the page attribute to become active markup, including event handlers, when the user triggers validation. Successful exploitation can execute JavaScript in a user's browser and compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.

Title
Cross-site Scripting (XSS) in Kendo UI for jQuery Menu
Summary
In Progress® Kendo® UI for jQuery prior to v2026.3.1015, the Menu component constructs HTML attributes from bound dataSource fields by string concatenation without proper neutralization. An attacker with low privileges who can control these fields can inject JavaScript event-handler attributes that execute when a user interacts with the affected Menu, compromising the confidentiality and integrity of data accessible in the user's browser context.

Title
Cross-Site Scripting via TabStrip, Menu, and PanelBar Image URLs in Kendo UI for jQuery
Summary
In Progress® Kendo® UI for jQuery prior to 2026.3.1015, the TabStrip, Menu, and PanelBar components insert data source imageUrl values into single-quoted image src attributes without proper escaping. An attacker who can modify an image URL can inject additional HTML attributes, including event handlers, and execute JavaScript in a user's browser when the affected component renders the image. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. The earliest affected version has not been confirmed. This issue is fixed in version 2026.3.1015.

Mitigation
Implementation

Carefully check each input parameter against a rigorous positive specification (allowlist) defining the specific characters and format allowed. All input should be neutralized, not just parameters that the user is supposed to specify, but all data in the request, including hidden fields, cookies, headers, the URL itself, and so forth. A common mistake that leads to continuing XSS vulnerabilities is to validate only fields that are expected to be redisplayed by the site. We often encounter data from the request that is reflected by the application server or the application that the development team did not anticipate. Also, a field that is not currently reflected may be used by a future developer. Therefore, validating ALL parts of the HTTP request is recommended.

Strategy: Output Encoding

  • Use and specify an output encoding that can be handled by the downstream component that is reading the output. Common encodings include ISO-8859-1, UTF-7, and UTF-8. When an encoding is not specified, a downstream component may choose a different encoding, either by assuming a default encoding or automatically inferring which encoding is being used, which can be erroneous. When the encodings are inconsistent, the downstream component might treat some character or byte sequences as special, even if they are not special in the original encoding. Attackers might then be able to exploit this discrepancy and conduct injection attacks; they even might be able to bypass protection mechanisms that assume the original encoding is also being used by the downstream component.
  • The problem of inconsistent output encodings often arises in web pages. If an encoding is not specified in an HTTP header, web browsers often guess about which encoding is being used. This can open up the browser to subtle XSS attacks.

Implementation

With Struts, write all data from form beans with the bean's filter attribute set to true.

Strategy: Attack Surface Reduction

To help mitigate XSS attacks against the user's session cookie, set the session cookie to be HttpOnly. In browsers that support the HttpOnly feature (such as more recent versions of Internet Explorer and Firefox), this attribute can prevent the user's session cookie from being accessible to malicious client-side scripts that use document.cookie. This is not a complete solution, since HttpOnly is not supported by all browsers. More importantly, XmlHttpRequest and other powerful browser technologies provide read access to HTTP headers, including the Set-Cookie header in which the HttpOnly flag is set.

CAPEC-18: XSS Targeting Non-Script Elements

This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an adversary to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote adversary to collect and interpret the output of said attack.

CAPEC-193: PHP Remote File Inclusion

In this pattern the adversary is able to load and execute arbitrary code remotely available from the application. This is usually accomplished through an insecurely configured PHP runtime environment and an improperly sanitized "include" or "require" call, which the user can then control to point to any web-accessible file. This allows adversaries to hijack the targeted application and force it to execute their own instructions.

CAPEC-32: XSS Through HTTP Query Strings

An adversary embeds malicious script code in the parameters of an HTTP query string and convinces a victim to submit the HTTP request that contains the query string to a vulnerable web application. The web application then procedes to use the values parameters without properly validation them first and generates the HTML code that will be executed by the victim's browser.

CAPEC-86: XSS Through HTTP Headers

An adversary exploits web applications that generate web content, such as links in a HTML page, based on unvalidated or improperly validated data submitted by other actors. XSS in HTTP Headers attacks target the HTTP headers which are hidden from most users and may not be validated by web applications.
