Official Description

blueprintUE is a tool to help Unreal Engine developers. Prior to 4.2.0, when a password reset is initiated, a 128-character CSPRNG token is generated and stored alongside a password_reset_at timestamp. However, the token redemption function findUserIDFromEmailAndToken() queries only for a matching email + password_reset token pair — it does not check whether the password_reset_at timestamp has elapsed any maximum window. A generated reset token is valid indefinitely until it is explicitly consumed or overwritten by a subsequent reset request. This vulnerability is fixed in 4.2.0.
