CVE-2025-62418: 
PHP vulnerability analysis and mitigation

A Cross-Site Scripting (XSS) vulnerability was discovered in Bagisto v2.3.7, identified as CVE-2025-62418. The vulnerability was disclosed on October 16, 2025, affecting the TinyMCE image upload functionality in the Bagisto e-commerce platform. The issue allows attackers with sufficient privileges (such as admin) to upload malicious SVG files containing embedded JavaScript that executes in the context of the admin/user's browser (GitHub Advisory).

The vulnerability stems from improper handling of SVG file uploads in the TinyMCE editor integration. Since SVG files are XML-based, they can contain script or event handlers that execute when rendered. The application fails to validate file content or strip potentially dangerous elements such as , onload, onclick, foreignObject, xlink:href injection, and objects/embed tags. The vulnerability has been assigned a CVSS v3.1 base score of 6.9 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:N. The weakness is categorized under CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page) and CWE-87 (Improper Neutralization of Alternate XSS Syntax) (GitHub Advisory).

When exploited, the vulnerability allows stored malicious scripts to execute in the context of the admin/user's browser when the content is viewed. This can lead to session hijacking, unauthorized actions, or privilege escalation, particularly targeting other admin users or editors who view the compromised content (GitHub Advisory).

The vulnerability has been patched in Bagisto version 2.3.8. Users are advised to upgrade to this version or later to mitigate the risk (GitHub Advisory).
