CVE-2026-41938
HighSummary
Vvveb before version 1.0.8.2 contains an unrestricted file upload vulnerability in the media upload handler that allows authenticated users with media-upload permissions to bypass extension restrictions by uploading a .htaccess file. This enables attackers to upload .phtml files containing arbitrary PHP code and execute the payload through an unauthenticated HTTP GET request.
Risk Assessment
The organization is at risk of remote code execution with web server privileges, potentially leading to serious security breaches and data loss.
Recommendation
It is recommended to update Vvveb to version 1.0.8.2 or later and implement additional security measures to restrict unauthorized file uploads.

Original NVD description (English source)
Vvveb before version 1.0.8.2 contains an unrestricted file upload vulnerability in the media upload handler that allows authenticated users with media-upload permissions to bypass extension restrictions by uploading a .htaccess file to map .phtml extensions to the PHP handler. Attackers can upload a .phtml file containing arbitrary PHP code and execute the uploaded payload through a subsequent unauthenticated HTTP GET request to the uploaded file, resulting in remote code execution with web server privileges.
