## Technical details

This is a path traversal vulnerability (CWE-22) in the File::sanitizePath() function within Laravel-Mediable versions before 7.0.0. The vulnerability stems from an insufficiently restrictive regex pattern in the sanitization logic that permits both dot (.) and forward slash (/) characters, combined with an ineffective trailing trim() operation. This allows an attacker who has authentication privileges and can control the directory argument passed to MediaUploader::toDestination() to bypass path sanitization. An authenticated attacker can exploit this to write uploaded files to sensitive locations including the application root, configuration directories containing environment variables, or other writable directories, leading to remote code execution if PHP files are uploaded. The patch is available in version 7.0.0 and later.
