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."}, {"lang": "es", "value": "Glances es una herramienta de monitorizaci\u00f3n de sistemas multiplataforma de c\u00f3digo abierto.
