Technical description
Frappe is a full-stack web application framework. Prior to 15.115.0 and 16.27.0, the public request-data web form and PersonalDataDownloadRequest class in frappe/website/doctype/personal_data_download_request/personal_data_download_request.py return distinguishable response shapes for registered and unregistered email addresses, including the user_name field and persistence behavior. A remote attacker can compare the responses to enumerate registered users. This issue is fixed in versions 15.115.0 and 16.27.0.
