Quick assessment

Affected

CVE-2026-125637

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.

在 Konflux UI 代理中发现一处缺陷：KonfluxUI 自定义资源中定义的域名值会被直接插入到代理配置文件，而未经过充分的验证或清理。拥有修改该自定义资源权限的已认证用户可以注入恶意配置指令，从而绕过身份验证和访问控制机制，可能导致内部后端服务暴露。此外，提供格式错误的输入会导致配置生成器失败，进而阻止代理启动，造成拒绝服务（DoS）攻击。

Vulnerability Title

Konflux-ci: unvalidated hostname fields enable caddyfile config injection in the konflux ui proxy generator, allowing an unauthenticated route to be spliced ahead of the forward_auth/impersonate authorization chain

Source: CVE Program / CVE List V5

Vulnerability Description

A flaw was found in the Konflux UI proxy. Hostname values defined in the KonfluxUI custom resource are inserted directly into proxy configuration files without adequate validation or sanitization. An authenticated user with permissions to modify the custom resource can inject malicious configuration directives to bypass authentication and authorization controls, potentially exposing internal backend services. In addition, providing malformed input can cause the configuration generator to fail, resulting in a denial of service (DoS) by preventing the proxy from starting.
