Zammad 是一款基于 Web 的开源帮助台/客户支持系统。在 7.0.2 版本之前，当多个知识库（KB）分类分配了不同的编辑器角色时，拥有某个分类中 权限的用户，可以通过全局快速搜索功能，查看到其他其无权编辑的分类中的答案标题和更新时间戳。虽然分类名称不会被泄露，且打开答案后会返回“页面未找到”，但仅标题本身也可能导致敏感信息泄露。该漏洞已在 7.0.2 版本中修复。

Vulnerability Title
Zammad: Titles of knowledge base answers will be shown across all categories via the global search
Source: CVE Program / CVE List V5
Vulnerability Description
Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, when multiple KB categories have different editor roles assigned, a user with knowledge_base.editor in one category can see answer titles and updated_at timestamps from categories they do not have editor access to , via the global quick search. Category names are not leaked, and opening the answer returns "Page not found," but the title alone may disclose sensitive information. This vulnerability is fixed in 7.0.2.
