Summary
FileBrowser Quantum has Username Enumeration via Authentication Timing Side-Channel
Details

FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to version 1.3.2-beta, the /api/auth/login authentication endpoint does not execute in constant time. When a non-existent username is supplied, the server returns a 401/403 response almost immediately. When a valid username is provided, the server performs a bcrypt password comparison, causing a measurable delay in the response time. Version 1.3.2-beta patches the issue.
