Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
File Browser (github.com/filebrowser/filebrowser/v2) versions before 2.63.17 return the bcrypt password hash and bypass token of password-protected shares in share API responses. Any authenticated user can read these values for their own shares, and an administrator listing shares through the API can read them for all users' shares. An attacker holding them could crack the share password offline or open the protected share without knowing the password. Upgrade to version 2.63.17 or later.
