WSO2 products vulnerable to privilege escalation due to business logic flaw in SOAP admin services

A privilege escalation vulnerability exists in multiple WSO2 products due to a business logic flaw in SOAP admin services. A malicious actor can create a new user with elevated permissions only when all of the following conditions are met:

• SOAP admin services are accessible to the attacker.
• The deployment includes an internally used attribute that is not part of the default WSO2 product configuration.
• At least one custom role exists with non-default permissions.
• The attacker has knowledge of the custom role and the internal attribute used in the deployment.

Exploiting this vulnerability allows malicious actors to assign higher privileges to self-registered users, bypassing intended access control mechanisms.
