{"id":"DEBIAN-CVE-2026-32610","details":"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.","modified":"2026-09-14T17:03:06.928438453Z","published":"2026-03-18T17:16:06.947Z","upstream":["CVE-2026-32610"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-32610"}],"affected":[{"package":{"name":"glances","ecosystem":"Debian:12","purl":"pkg:deb/debian/glances?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.1.1+dfsg-1","3.4.0.3+dfsg-1","4.0.5+dfsg-1","4.1.2.1+dfsg-1","4.2.1+dfsg-1","4.3.0.8+dfsg-1","4.3.1+dfsg-1","4.3.3+dfsg-1","4.5.1+dfsg-1","4.5.2+dfsg-1","4.5.3.2+dfsg-1","4.5.4+dfsg-1","4.5.5+dfsg-1","4.5.6+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32610.json"}},{"package":{"name":"glances","ecosystem":"Debian:13","purl":"pkg:deb/debian/glances?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.1+dfsg-1","4.3.3+dfsg-1","4.5.1+dfsg-1","4.5.2+dfsg-1","4.5.3.2+dfsg-1","4.5.4+dfsg-1","4.5.5+dfsg-1","4.5.6+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32610.json"}},{"package":{"name":"glances","ecosystem":"Debian:14","purl":"pkg:deb/debian/glances?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.5.2+dfsg-1"}]}],"versions":["4.3.1+dfsg-1","4.3.3+dfsg-1","4.5.1+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32610.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
