Summary
Frappe CRM versions before 1.81.2 lack authorization checks on CRM Notification records because permission hooks are missing. An authenticated user with the Sales User role can read, mark as read, or delete notifications belonging to other users. An attacker can query frappe.client endpoints filtered on to_user, or call mark_as_read with another user's name. The weakness is classified as CWE-862 (Missing Authorization).
