Technical details
The vulnerability is a username enumeration flaw in WSO2 products configured with external user stores. During authentication attempts, the system returns distinct responses that leak information about whether a given username exists, allowing attackers to probe the user store and build a valid user list. An unauthenticated remote attacker can exploit this over the network without special privileges.
