Description
Fleet is open source device management software. Prior to 4.81.0, a vulnerability in Fleet’s password management logic could allow previously issued password reset tokens to remain valid after a user changes their password. As a result, a stale password reset token could be reused to reset the account password even after a defensive password change. Version 4.81.0 patches the issue.
