If an attacker has access to the data source, the leaked token could be used to authenticate to Grafana.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://github.com/grafana/bugbounty/security/advisories/GHSA-5585-m9r5-p86j","https://grafana.com/security/security-advisories/cve-2023-1387/","https://security.netapp.com/advisory/ntap-20230609-0003/","https://github.com/grafana/bugbounty/security/advisories/GHSA-5585-m9r5-p86j","https://grafana.com/security/security-advisories/cve-2023-1387/"],"products":["grafana:grafana"],"source":"nvd","synced_at":"2026-10-19T21:38:05.473481323+00:00"},"epss":{"cve":"CVE-2023-1387","score":0.01504,"percentile":0.74348,"date":"2026-10-31"},"kev":null,"osv":[],"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).
