CVE-2026-111939
Frappe Helpdesk before 1.26.0 contains an authorization bypass vulnerability that allows authenticated portal users to create tickets impersonating other customers by supplying a raised_by value.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
