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.
