CVE-2022-40816 Information

Description

Zammad 5.2.1 is vulnerable to Incorrect Access Control. Zammad’s asset handling mechanism has logic to ensure that customer users are not able to see personal information of other users. This logic was not effective when used through a web socket connection so that a logged-in attacker would be able to fetch personal data of other users by querying the Zammad API. This issue is fixed in 5.2.2.
