Ose-oauth-server: oauth-server: open redirect vulnerability enables phishing via unvalidated parameter. PUBLISHED

Description (CNA)

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.
