The record
A flaw was found in the oauth-server component. This open redirect vulnerability occurs when the 'then' parameter in the grant approval handler is not properly validated. A remote attacker can craft a malicious URL that, when approved or denied by an authenticated user, redirects them to an attacker-controlled website. This could enable phishing attacks, potentially tricking users into revealing sensitive information.
