An open redirection vulnerability exists in multiple WSO2 products due to improper validation of the multi-option URL in the authentication endpoint when multi-option authentication is enabled. A malicious actor can craft a valid link that redirects users to an attacker-controlled site. By exploiting this vulnerability, an attacker may trick users into visiting a malicious page, enabling phishing attacks to harvest sensitive information or perform other harmful actions.
Solution:
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
