Description

Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, summary An issue with permission checks in the knowledge base management area has been identified. Under certain conditions, data validation for linked items was not fully enforced. This could have allowed users with limited read permissions to interact with items outside their assigned access scope. Data access has been strengthened in the current version through additional validation routines. This issue is fixed in version 7.0.2.
