How to fix

Fixed in: 1.74.0

Technical details

The vulnerability is an authorization bypass in the add_note_to_call_log and add_task_to_call_log API endpoints that lack permission validation before modifying call log records. An authenticated Sales User can supply an arbitrary call_sid parameter to attach notes and tasks to any call log without checking if the user has write access to that specific record. The fix adds an explicit frappe.has_permission("CRM Call Log", "write", call_sid) check before allowing modifications.

Affected products

Frappe CRM before 1.74.0
