A missing authorization vulnerability allows any authenticated user—including those with minimal portal or no-role access—to enumerate and view private calendar events and task records by supplying arbitrary parameters to the activities API. This could expose sensitive business information and private scheduling details to unauthorized users.

How to fix

Fixed in: ERPNext 15.121.4, 16.36.0

Technical details

The get_open_activities function in erpnext.crm.utils fails to enforce proper authorization checks when returning ToDo and Event records based on user-supplied ref_doctype and ref_docname parameters. An authenticated attacker can call this API endpoint with arbitrary values to enumerate activities and calendar events they should not have access to. No authentication bypass is required—the vulnerability is exploitable by any logged-in user, including those with restricted or no explicit roles.
