    在 roundcube（一種基於 AJAX 的 IMAP 伺服器可剝皮網路郵件解決方案）中發現多個漏洞，這可能導致 IMAP 命令插入、跨網站指令碼、繞過 SSRF、電子郵件標頭插入、CSS 屬性插入、繞過遠端內容封鎖、資訊洩露或權限提升。

    針對穩定的發行版本 (trixie)，這些問題已在 1.6.20+dfsg-0+deb13u1 版本中修復。

    建議您升級 roundcube 套件。

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。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - Roundcube Webmail 之前 1.6.20 和 1.7.x 以前 1.7.5 受到多主机安装中的一个错误认证漏洞的影响。当用户使用别名地址登录时，rcube_user：：query（） 会在未验证 IMAP 主机查找的情况下将地址与身份记录进行匹配，因此登录可能会解析为属于其他 IMAP 主机的用户帐户。上游在提交修复了 IMAP 主机不限定别名登录这一缺陷中修复了此问题。（CVE-2026-114732）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

远程 Debian 13 主机上存在安装的程序包，该程序包受到 dsa-6579 公告中提及的多个漏洞的影响。

    Multiple vulnerabilities were discovered in roundcube, a skinnable AJAX     based webmail solution for IMAP servers, which could result in IMAP     command injection, cross-site scripting, SSRF bypass, email header     injection, css property injection, remote content blocking bypass,     information disclosure or privilege escalation.

    For the stable distribution (trixie), these problems have been fixed in     version 1.6.20+dfsg-0+deb13u1.

    We recommend that you upgrade your roundcube packages.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an improper authentication     vulnerability in multi-host installations. When a user logs in with an alias address, rcube_user::query()     matched the address against identity records without qualifying the lookup by IMAP host, so a login could     be resolved to a user account belonging to a different IMAP host. Upstream fixed this in the commit Fix     bug where an alias login wasn't qualified by IMAP host. (CVE-2026-114732)

Note that Nessus relies on the presence of the package as reported by the vendor.
