Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Code16/sharp, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A Cross-Site Scripting (XSS) vulnerability was discovered in code16/sharp when rendering content using the SharpShowTextField component. In affected versions, expressions wrapped in `{{` & `}}` were evaluated by Vue. This allowed attackers to inject arbitrary JavaScript or HTML that executes in the browser when the field is displayed. For example, if a field’s value contains `{{ Math.random() }}`, it will be executed instead of being displayed as text. ### Impact Attackers who can control content rendered through SharpShowTextField could execute arbitrary JavaScript in the context of an authenticated user’s browser. This could lead to: - Theft of user session tokens. - Unauthorized actions performed on behalf of users. - Injection of malicious content into the admin panel. ### Patches The issue has been fixed in v9.11.1 of code16/sharp package. ### Mitigation / Workarounds Sanitize or encode any user-provided data that may include (`{{` & `}}`) before displaying it in a SharpShowTextField.
