FKIE_CVE-2026-32610

Vulnerability from fkie_nvd - Published: 2026-03-18 17:16 - Updated: 2026-03-21 00:16
Severity
8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
Summary
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.

Esto otorga efectivamente a cualquier sitio web la capacidad de realizar solicitudes API de origen cruzado con credenciales al servidor de Glances, lo que permite el robo de datos entre sitios de informaci\u00f3n de monitorizaci\u00f3n del sistema, secretos de configuraci\u00f3n y argumentos de l\u00ednea de comandos de cualquier usuario que tenga una sesi\u00f3n de navegador activa con una instancia de Glances.
