Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在当前开发版本的 Eclipse aeriOS（尚未发布正式版本）中，Federator 组件默认禁用了出站 HTTPS 连接的 TLS 证书校验。当环境变量 未设置或设置为 时，该组件会配置其 HTTP 传输层以跳过 TLS 证书验证。 因此，能够拦截 Federator 与外部服务之间网络通信的攻击者，可能冒充这些外部服务，并截获通过 HTTPS 传输的敏感信息，包括 OAuth 客户端凭据和 Bearer 令牌。 该问题已通过默认启用 TLS 证书校验得到修复。现在，在 Helm Chart 和 Docker

Source: CVE Program / CVE List V5
Vulnerability Description
In the current development version of Eclipse aeriOS, for which no official release has yet been published, the Federator component disables TLS certificate validation for outbound HTTPS connections by default. When the TLS_CERTIFICATE_VALIDATION environment variable is unset or set to false, the component configures its HTTP transport to skip TLS certificate verification. As a result, an attacker able to intercept network communications between the Federator and external services could impersonate those services and intercept sensitive information transmitted over HTTPS, including OAuth client credentials and bearer tokens. The issue has been addressed by enabling TLS certificate validation by default. The TLS_CERTIFICATE_VALIDATION environment variable is now set to true in the default configuration provided by the Helm chart and Docker Compose deployment.
