CVE-2025-62798: 
PHP vulnerability analysis and mitigation

A Cross-Site Scripting (XSS) vulnerability (CVE-2025-62798) was discovered in code16/sharp, a content management framework built for Laravel. The vulnerability was found in the SharpShowTextField component when rendering content. The issue was disclosed on October 28, 2025, affecting versions prior to 9.11.1. In affected versions, expressions wrapped in {{ & }} were evaluated by Vue, allowing attackers to inject arbitrary JavaScript or HTML that executes in the browser when the field is displayed (GitHub Advisory).

The vulnerability has been assigned a CVSS v3.1 base score of 5.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. The root cause was identified in the TextRenderer.vue component, which would take content and directly create a dynamic Vue component from it without proper sanitization. The vulnerability is classified as CWE-79: Improper Neutralization of Input During Web Page Generation (Miggo Analysis, GitHub Advisory).

The exploitation of this vulnerability could lead to several security implications: theft of user session tokens, unauthorized actions performed on behalf of users, and injection of malicious content into the admin panel. Attackers who can control content rendered through SharpShowTextField could execute arbitrary JavaScript in the context of an authenticated user's browser (GitHub Advisory).

The vulnerability has been patched in version 9.11.1 of the code16/sharp package. The fix includes the introduction of a sanitization function, sanitizeForVue, within TemplateRenderer.vue that escapes the {{ and }} sequences, preventing Vue from interpreting them as expressions. For those unable to update immediately, it is recommended to sanitize or encode any user-provided data that may include ({{ & }}) before displaying it in a SharpShowTextField (GitHub Advisory, Miggo Analysis).
