Glances's Default CORS Configuration Allows Cross-Origin Credential Theft

Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, the Glances REST API web server ships with a default CORS configuration that sets `allow_origins=["*"]` combined with `allow_credentials=True`. When both of these options are enabled together, Starlette's `CORSMiddleware` reflects the requesting `Origin` header value in the `Access-Control-Allow-Origin` response header instead of returning the literal `*` wildcard. This effectively grants any website the ability to make credentialed cross-origin API requests to the Glances server, enabling cross-site data theft of system monitoring information, configuration secrets, and command line arguments from any user who has an active browser session with a Glances instance. Version 4.5.2 fixes the issue.

glances 安全漏洞

glances是Nicolas Hennion个人开发者的一款系统监测工具。 glances 4.5.2之前版本存在安全漏洞，该漏洞源于默认CORS配置允许任意网站进行凭据跨域API请求，可能导致跨站窃取系统监控信息和配置机密。
