In version 4.9.0, Chartbrew exposes POST /api/chart/:chart_id/query without authentication. The endpoint only checks team.allowReportRefresh and does not verify that the target chart belongs to a public report, that the project is public, or that sharing policy allows the operation. An unauthenticated attacker who knows a chart identifier can trigger a data refresh and retrieve the current data of private charts. This issue has been patched in version 5.0.0.","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-862"],"references":["https://github.com/chartbrew/chartbrew/releases/tag/v5.0.0","https://github.com/chartbrew/chartbrew/security/advisories/GHSA-cpr6-mhgm-893w"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-40601","score":0.00326,"percentile":0.25758,"date":"2026-11-01"},"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).
