4DescriptionGitHub Advisory
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to 2.57.1, a case-sensitivity flaw in the password validation logic allows any authenticated user to change their password (or an admin to change any user's password) without providing the current password. By using Title Case field name "Password" instead of lowercase "password" in the API request, the current_password verification is completely bypassed. This enables account takeover if an attacker obtains a valid JWT token through XSS, session hijacking, or other means. This vulnerability is fixed in 2.57.1.
AnalysisAI
Filebrowser versions prior to 2.57.1 allow authenticated users to reset passwords without verifying the current password due to case-sensitive validation logic that can be bypassed using mixed-case field names in API requests. An attacker with a valid JWT token obtained through XSS, session hijacking, or similar means could exploit this to perform account takeover. Public exploit code exists for this vulnerability, and a patch is available.
