What is CVE-2026-124314?

Frappe's ERPNext platform, in versions prior to 15.121.4 and 16.36.0, is affected by a missing authorization issue within the erpnext.crm.utils.get_open_activities function. This vulnerability allows any authenticated user, including those with portal access or lacking specific roles, to manipulate the ref_doctype and ref_docname parameters. Consequently, this exploitation could lead to the enumeration of ToDo and private calendar event records, potentially exposing sensitive user data.
