Directus has an Open Redirect via Parser Bypass in OAuth2/SAML Authentication Flow

Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.16.1, an open redirect vulnerability exists in the login redirection logic. The isLoginRedirectAllowed function fails to correctly identify certain malformed URLs as external, allowing attackers to bypass redirect allow-list validation and redirect users to arbitrary external domains upon successful authentication. This vulnerability is fixed in 11.16.1.
