Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, a security filter that protects Zammad's AI Agent configuration can be bypassed by entering specially crafted text into one of an AI Agent's fields. An administrator with permission to create or edit AI Agents could exploit this to run arbitrary commands on the server that hosts Zammad, potentially reading, modifying, or destroying all data stored on that server.
No interaction from other users is needed; the malicious code runs automatically the next time the affected AI Agent processes a ticket. This issue is fixed in version 7.1.2.
