Description
Webreaper Damselfly through 4.5.3 contains an authentication bypass vulnerability that allows unauthenticated attackers to access all /api/* routes because controller authorization attributes are commented out. Attackers can send PUT /api/users with Admin roles to create administrator accounts, or POST /api/users to reset any user's password, gaining full control.
