In core/doctype/preparedreport/preparedreport.py in Frappe 11 and 12, data files generated with Prepared Report were being stored as public files (no authentication is required to access; having a link is sufficient) instead of private files.
public/js/frappe/form/footer/timeline.js in Frappe Framework 12 through 12.0.8 does not escape HTML in the timeline and thus is affected by crafted "changed value of" text.
An issue was discovered in Frappe Framework 10, 11 before 11.1.46, and 12. There exists an XSS vulnerability.
Frappe Framework 12 and 13 does not properly validate the HTTP method for the frappe.client API.
