Description

An issue was discovered in Deskpro before 2019.8.0. The /api/tickets endpoint failed to properly validate a user's privilege, allowing an attacker to retrieve arbitrary information about all helpdesk tickets stored in database with numerous filters. This leaked sensitive information to unauthorized parties. Additionally, it leaked ticket authentication code, making it possible to make changes to a ticket.

Affected products

• Deskpro: before 2019.8.0 — fixed in 2019.8.0

Upgrade to a fixed version: Deskpro 2019.8.0. Check the vendor advisory for mitigations.
