Name of the Vulnerable Software and Affected Versions
Zammad versions prior to 7.0.2
Description
An authorization bypass exists where a customer with access to a ticket can download attachments from internal ticket articles. While the article listing API correctly hides internal articles, the attachment download endpoint only verifies access to the parent ticket and fails to check the authorization level of the specific article. This allows unauthorized users to retrieve sensitive files attached to internal notes.
Recommendations
Update to version 7.0.2.
