There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions 2.28.1 and prior have a Privilege
    Escalation vulnerability where insufficient access control checks in ProjectUsersAddCommand
    (manage_proj_user_add.php) allow users having manage_project_threshold access level (manager by default)
    to grant project-level administrator access to any user (including themselves) in any Project they have
    manager rights in. The normal project-user add form restricts the selectable access levels to the actor's
    own project role or below. However, the backend handler still accepts a forged higher access_level value
    and writes it. The consequences of the privilege escalation are slight, as having administrator access at
    Project level is effectively not very different from being manager, and it does not actually give
    administrator privileges on the whole MantisBT instance. In particular, it does not let the upgraded user
    delete the Project or grant them any access to global administrative functions such as managing Users,
    Projects, Plugins, Custom Fields, etc. This issue has been fixed in version 2.28.2. (CVE-2026-34390)

遠端主機上安裝的 MantisBT 版本比 2.28.2 舊。因此，會受到多個弱點影響：

  - MantisBT 容易受到從管理員到管理員的權限提升。（CVE-2026-34390）

  - MantisBT 在透過問題更新 API 編輯錯誤說明時容易受到授權繞過。（CVE-2026-42070）

  - MantisBT 容易受到自訂欄位文字區域值中儲存的 XSS 的影響。（CVE-2026-39960）

請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

远程主机上安装的 MantisBT 版本低于 2.28.2。因此，该应用程序受到多个漏洞的影响：

  - MantisBT 容易受到从管理员到管理员的权限升级漏洞的影响。（CVE-2026-34390）

  - MantisBT 容易受到通过问题更新 API 在缺陷注释编辑中绕过授权的影响。（CVE-2026-42070）

  - MantisBT 容易受到自定义字段 textarea 值中存储的 XSS 的影响。（CVE-2026-39960）

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

リモートホストにインストールされている MantisBT のバージョンは、2.28.2 より前です。そのため、以下の複数の脆弱性の影響を受けます。

  - MantisBT は、マネージャーから管理者への権限昇格に脆弱です。(CVE-2026-34390)

  - MantisBT は、Issue Update API を介したバグノート編集の承認バイパスに対して脆弱性があります。(CVE-2026-42070)

  - MantisBT は、カスタムフィールドテキストエリア値に保存された XSS に脆弱です。(CVE-2026-39960)

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

The version of MantisBT installed on the remote host is prior to 2.28.2. It is, therefore, affected by multiple vulnerabilities:

  - MantisBT is vulnerable to Privilege Escalation from Manager to Administrator. (CVE-2026-34390)

  - MantisBT is vulnerable to Authorization Bypass in Bugnote Editing via Issue Update API. (CVE-2026-42070)

  - MantisBT is vulnerable to Stored XSS in Custom Field Textarea Values. (CVE-2026-39960)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
