{"id":"CVE-2026-68517","summary":"Glances: REST API CORS Credentials Guard Uses Exact-Match Instead of Membership Test — Bypassed by Any Multi-Origin Allowlist Containing the Wildcard","details":"Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, the cors_origins guard in glances/outputs/glances_restful_api.py uses exact list equality instead of wildcard membership, allowing a multi-origin list containing the wildcard to retain cors_credentials and expose authenticated REST API data to an untrusted website visited by a previously authenticated user. This issue is fixed in 4.5.6.","aliases":["GHSA-fp27-88fp-2phg","PYSEC-2026-3667"],"modified":"2026-09-03T10:10:55.065823417Z","published":"2026-08-17T17:03:23.346Z","related":["openSUSE-SU-2026:11674-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-942"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68517.json"},"references":[{"type":"WEB","url":"https://github.com/nicolargo/glances/releases/tag/v4.5.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68517.json"},{"type":"ADVISORY","url":"https://github.com/nicolargo/glances/security/advisories/GHSA-fp27-88fp-2phg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68517"},{"type":"FIX","url":"https://github.com/nicolargo/glances/commit/890858944ab9d03730ec6b1ba42d4015e6d85db5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nicolargo/glances","events":[{"introduced":"0"},{"fixed":"890858944ab9d03730ec6b1ba42d4015e6d85db5"},{"fixed":"ce2f8506289c71e48ed8bf186f2c04d8256203d5"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.5.6"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v4.5.5","v4.5.4","v4.5.3","v4.5.2","v4.5.1","v4.5.0.5","v4.5.0.4","v4.5.0.3","v4.5.0.2","v4.5.0.1","v4.5.0","v4.4.1","v4.4.0","v4.3.3","v4.3.2","v4.3.1","v4.3.0.8","v4.3.0.7","v4.3.0.6","v4.3.0.3","v4.3.0.2","v4.3.0.1","v4.3.0","v4.2.0","v3.4.0","v3.3.1","v3.3.0.1","v3.3.0","v3.2.7","v3.2.6","v3.2.5","v3.2.4.2","v3.2.4.1","v3.2.4","v3.2.3.1","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.7","v3.1.6.1","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0","v2.11","v2.10","v2.9.1","v2.9.0","v2.8.8","v2.8.7","v2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8","v2.7.1","v2.7","v2.7_RC1","v2.5.1","v2.5","v2.4.2","v2.4.1","v2.3","v2.2","v1.7.3","v1.7.2","v1.7.1","v1.7","v1.6.1","v1.6","v1.5.2","v1.5.1","v1.5","v1.4.2.1","v1.4.2","v1.4.1.1","v1.4.1","v1.4","v1.3.7","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3","v1.2","v1.1.3","v1.1.2","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68517.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:N/A:N"}]}
