{"id":"CVE-2026-40601","summary":"Chartbrew: Missing Authorization in /api/chart/:chart_id/query via team-level refresh toggle","details":"Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. 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.","aliases":["GHSA-cpr6-mhgm-893w"],"modified":"2026-08-04T11:50:53.939925770Z","published":"2026-04-30T18:22:43.557Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40601.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-862"]},"references":[{"type":"WEB","url":"https://github.com/chartbrew/chartbrew/releases/tag/v5.0.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40601.json"},{"type":"ADVISORY","url":"https://github.com/chartbrew/chartbrew/security/advisories/GHSA-cpr6-mhgm-893w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40601"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/chartbrew/chartbrew","events":[{"introduced":"7cf1713c5a14d36cf88f4e5f467ddc74d7c6f600"},{"last_affected":"7cf1713c5a14d36cf88f4e5f467ddc74d7c6f600"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"= 4.9.0"},{"last_affected":"= 4.9.0"}]}}],"versions":["= 4.9.0","v4.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40601.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
