Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
File Browser (github.com/filebrowser/filebrowser/v2) before 2.34.1 lets users set trivial passwords, uses a well-known default password for the initial admin account, and has no brute-force protection on the login endpoint. An attacker with network access to the login endpoint can guess passwords for accounts, possibly including administrator accounts. Upgrade to version 2.34.1 or later. The older github.com/filebrowser/filebrowser module, version 1.11.0 and earlier, has no fixed version listed.
