CVE-2026-111938
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.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
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.
