CVE-2022-48023Network attack vector

Unauthorized ticket-tag changes via missing permission check

Published Feb 3, 2023 · Updated Aug 3, 2024

Incorrect access control in Zammad 5.3.0 allows remote authenticated users to change tags on their own customer tickets through the API. The ticket-tag update path does not require an agent role or ticket write permission before applying a requested tag change. A customer account is sufficient, and the impact is limited to unauthorized tag modification on tickets belonging to that customer.
