The vulnerability in Frappe allows a remote attacker to enumerate registered users by exploiting the distinguishable response shapes returned by the public request-data web form and the PersonalDataDownloadRequest class for registered versus unregistered email addresses. This could lead to unauthorized access to user information, posing a risk to user privacy and security. Organizations using affected versions should prioritize updating to versions 15.115.0 or 16.27.0 to mitigate this risk.

Original NVD 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.
