Frappe is a full-stack web application framework. Prior to 15.116.0 and 16.29.0, the OAuth login flow uses an unsanitized client-controlled state parameter to select post-authentication navigation, allowing a crafted state value to redirect a user to an attacker-chosen location. This issue is fixed in versions 15.116.0 and 16.29.0.
