| CVE-2022-40817 | 1 Zammad | 1 Zammad | 2025-05-21 | N/A | 4.3 MEDIUM |
|
Zammad 5.2.1 has a fine-grained permission model that allows to configure read-only access to tickets. However, agents were still wrongly able to perform some operations on such tickets, like adding and removing links, tags. and related answers. This issue has been fixed in 5.2.2.

| CVE-2022-40816 | 1 Zammad | 1 Zammad | 2025-05-21 | N/A | 6.5 MEDIUM |
|
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.

|
Zammad 5.2.0 is vulnerable to privilege escalation. Zammad has a prevention against brute-force attacks trying to guess login credentials. After a configurable amount of attempts, users are invalidated and logins prevented. An attacker might work around this prevention, enabling them to send more than the configured amount of requests before the user invalidation takes place.
