# Frappe Helpdesk: portal users can create tickets as other customers

Frappe Helpdesk before 1.26.0 lets an authenticated portal user set the raised_by field when creating a ticket, so the ticket is filed under another customer's email. The same flaw lets the attacker plant phishing tickets in a victim's portal and read the victim's replies through get_ticket_activities.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Helpdesk version (`bench version` or the app list in the Frappe bench) and confirm it is below `1.26.0`
- Review whether portal users can reach the hd_ticket.api.new endpoint

## Fix

- Upgrade Frappe Helpdesk to `1.26.0` or later
- Restart the bench after upgrading

## Timeline

## From the sources

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. Attackers can call the hd_ticket.api.new endpoint with a victim's email to plant phishing tickets in their portal and read their replies via get_ticket_activities.
