CVE-2024-40513Public exploitNetwork attack vector

Authenticated code execution via unrestricted profile upload

Published Jan 16, 2025 · Updated Feb 3, 2025

Unrestricted file upload in Themesbrand Chatvia 5.3.2 allows remote authenticated users to execute code through profile images. The User profile Upload image function accepts attacker-controlled file type and content, stores an HTML file containing JavaScript, and exposes its URL. A valid account and user interaction with the uploaded file are required; the published evidence demonstrates browser script execution, while the CVE record reports arbitrary code execution.
