CVE-2026-107812— Nginx UI: Self-upgrade runs an unsigned binary verified only by a same-origin digest → RCE via a compromised mirror or MITM

Quick assessment

Affected
0xJacky nginx-ui
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Nginx UI 是 Nginx Web 服务器的 Web 用户界面。从版本 2.0.0 到 2.5.0，其自升级机制仅使用来自同一升级镜像的相同源（same-origin）摘要对下载的二进制文件进行验证。如果升级镜像被攻陷，或网络攻击者能够同时篡改这两个响应，就可以提供恶意可执行文件及其匹配的摘要。该漏洞需要由操作员触发的升级才能生效，并且在下一次升级时，应用程序会在 Nginx UI 进程上下文中安装并执行攻击者控制的代码。此问题已在版本 2.5.0 中得到修复。

Vulnerability Title
Nginx UI: Self-upgrade runs an unsigned binary verified only by a same-origin digest → RCE via a compromised mirror or MITM
Source: CVE Program / CVE List V5
Vulnerability Description
Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, the self-upgrade mechanism validates a downloaded binary only with a same-origin digest obtained from the same upgrade mirror. A compromised mirror or network attacker able to alter both responses can supply a malicious executable and matching digest. An operator-triggered upgrade is required, and the application installs and runs the attacker-controlled code in the Nginx UI process context on the next upgrade. This issue is fixed in version 2.5.0.
