Description

Zammad is a web based open source helpdesk/customer support system. In 7.0.3 and 7.1.1, an authenticated administrator can obtain stored integration credentials in cleartext through the integration administration API. Certain responses do not consistently mask sensitive fields, so configured secrets can be returned in plain text instead of the expected masked placeholder. Both the LDAP and Exchange integrations are affected. This issue is fixed in version 7.1.2.
