{"cve":"CVE-2026-46608","nvd":{"published":"2026-06-25T19:16:37.663","modified":"2026-10-25T22:10:00.150","status":"Deferred","description":"Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances XML-RPC server (glances -s) introduced a configurable CORS origin list in version 4.5.3 as a mitigation for CVE-2026-33533. However, the implementation silently falls back to Access-Control-Allow-Origin: * whenever cors_origins contains more than one entry. An operator who configures an explicit two-entry allowlist (e.g. two internal dashboard origins) intending to restrict browser access instead receives the unrestricted wildcard. A malicious web page served from any origin can issue a CORS simple request to /RPC2 and read the full system monitoring dataset without the victim's knowledge. This vulnerability is fixed in 4.5.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N","score":7.4},"cwes":["CWE-183","CWE-942"],"references":["https://github.com/nicolargo/glances/releases/tag/v4.5.5","https://github.com/nicolargo/glances/security/advisories/GHSA-87qc-fj39-wccr"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-46608","score":0.00401,"percentile":0.34036,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-87qc-fj39-wccr","url":"https://osv.dev/vulnerability/GHSA-87qc-fj39-wccr","summary":"Glances: XML-RPC Multi-Origin CORS Configuration Silently Falls Back to Wildcard (Incomplete Fix for CVE-2026-33533)","modified":"2026-07-21T15:00:42.313199896Z","packages":[{"ecosystem":"PyPI","name":"glances","purl":"pkg:pypi/glances","ranges":["<4.5.5"],"fixed":["4.5.5"]}]},{"id":"PYSEC-2026-2495","url":"https://osv.dev/vulnerability/PYSEC-2026-2495","summary":"Glances: XML-RPC Multi-Origin CORS Configuration Silently Falls Back to Wildcard (Incomplete Fix for CVE-2026-33533)","modified":"2026-07-13T16:31:32.941014038Z","packages":[{"ecosystem":"PyPI","name":"glances","purl":"pkg:pypi/glances","ranges":["<4.5.5"],"fixed":["4.5.5"]}]}],"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).
