CVE-2025-62798: Sharp user-provided input can be evaluated in a SharpShowTextField with Vue template syntax
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.
