glances: Glances is an open-source system cross-platform monitoring tool
CVE-2026-32610 is fixed in glances on 1 platform by DEBIAN-CVE-2026-32610 (version 4.5.2+dfsg-1), released March 18, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
