{"cve":"CVE-2026-32610","nvd":{"published":"2026-03-18T17:16:06.947","modified":"2026-06-17T10:36:05.740","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-942"],"references":["https://github.com/nicolargo/glances/commit/4465169b71d93991f1e49740fe02428291099832","https://github.com/nicolargo/glances/releases/tag/v4.5.2","https://github.com/nicolargo/glances/security/advisories/GHSA-9jfm-9rc6-2hfq"],"products":["nicolargo:glances"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32610","score":0.00345,"percentile":0.28054,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9jfm-9rc6-2hfq","url":"https://osv.dev/vulnerability/GHSA-9jfm-9rc6-2hfq","summary":"Glances's Default CORS Configuration Allows Cross-Origin Credential Theft","modified":"2026-07-13T07:26:38.643592383Z","packages":[{"ecosystem":"PyPI","name":"glances","purl":"pkg:pypi/glances","ranges":["<4.5.2"],"fixed":["4.5.2"]}]},{"id":"PYSEC-2026-2169","url":"https://osv.dev/vulnerability/PYSEC-2026-2169","summary":"","modified":"2026-07-13T07:15:31.545227167Z","packages":[{"ecosystem":"PyPI","name":"glances","purl":"pkg:pypi/glances","ranges":["<4.5.2"],"fixed":["4.5.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
