When a user attempts to register with an existing username, the system responds with an error message that explicitly indicates the username is already in use.\n\nThis behavior allows an attacker to discover valid usernames within the system. The discovery of valid usernames can facilitate subsequent attacks such as brute force, social engineering, and targeted phishing campaigns.", "affected": [ { "vendor": "WSO2", "product": "WSO2 API
