CVE-2025-52078 Details

A file upload vulnerability has been identified in the Writebot AI Content Generator SaaS React Template, affecting versions through 4.0.0. This vulnerability allows remote attackers to gain escalated privileges by sending a crafted POST request to the /file-upload endpoint. The issue arises from inadequate validation of file types and extensions, coupled with the absence of authentication or session checks. As a result, attackers can upload malicious PHP files disguised as images and execute arbitrary commands once the files are placed in a publicly accessible directory.

Developers are advised to require authentication for file uploads, validate and sanitize MIME types and file extensions, store uploaded files outside the webroot, randomize filenames, and restrict access to uploaded files.
