CVE-2026-14856 Detail

Description

A stored Cross-Site Scripting (XSS) vulnerability in the file upload functionality of the Media Manager in TastyIgniter v4.3.0, caused by insufficient validation and sanitization of SVG files. An authenticated user with low privileges can upload a malicious SVG file containing JavaScript code. When an administrator views that file, the code executes in the context of their browser. By chaining this vulnerability with a Cross-Site Request Forgery (CSRF) attack, an attacker can extract the administrator’s CSRF token and perform unauthorized actions—such as modifying credentials—thereby gaining full control of the administrative account.
