CVE-2024-1440: WSO2 is vulnerable to Open Redirect through multi-option URL in its authentication endpoint

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.
