Wso2 Carbon Identity Management Endpoint Util
Monthly
The self-registration flow in WSO2 Identity Server and related WSO2 identity/API management products returns a distinct error when a submitted username already exists, letting unauthenticated users enumerate valid accounts. Any remote party who can reach the self-registration endpoint can harvest a list of confirmed usernames, which then feeds credential-stuffing, brute-force, and targeted phishing campaigns. Rated CVSS 5.3 (medium) with confidentiality-only impact; no public exploit code or active exploitation is identified in the supplied data at time of analysis.
