What it is

Frappe CRM before 1.74.0 contains a missing authorization vulnerability that allows authenticated Sales Users to modify other users' call logs by supplying arbitrary call_sid values. Attackers can call the add_note_to_call_log and add_task_to_call_log endpoints to attach attacker-written notes and tasks that appear on victims' call logs, leads, and deals.
