{"id":"CVE-2026-61743","summary":"Chartbrew: DNS Rebinding SSRF Bypass in Outbound Request Validation","details":"Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.2, Chartbrew's server/modules/safeRequest.js calls validateOutboundUrl() to resolve and validate a target hostname, but request-promise performs a separate DNS resolution for the actual connection. An authenticated user who can create or test API connections and controls the target DNS name can return a public address during validation and a private address during the request, bypassing the protections implemented by server/modules/outboundTargetPolicy.js. This DNS rebinding condition can expose internal services, localhost resources, or cloud metadata endpoints. This issue is fixed in version 5.2.2.","aliases":["GHSA-9537-vm84-j26f"],"modified":"2026-09-24T03:30:25.791960487Z","published":"2026-09-21T21:38:47.673Z","database_specific":{"cwe_ids":["CWE-350"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61743.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/chartbrew/chartbrew/releases/tag/v5.2.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61743.json"},{"type":"ADVISORY","url":"https://github.com/chartbrew/chartbrew/security/advisories/GHSA-9537-vm84-j26f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61743"},{"type":"FIX","url":"https://github.com/chartbrew/chartbrew/commit/d38d745fe9e45563be8c33e4c7a17788ee6f13a3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/chartbrew/chartbrew","events":[{"introduced":"0"},{"fixed":"d38d745fe9e45563be8c33e4c7a17788ee6f13a3"},{"fixed":"e14ffa0705586f27a19e051d74263fa0a7f94426"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"5.2.2"}]}}],"versions":["v5.2.1","v5.2.0","v5.1.0","v5.0.1","v5.0.0","v4.9.0","v4.8.5","v4.8.4","v4.8.3","v4.8.2","v4.8.1","v4.8.0","v4.7.0","v4.6.0","v4.5.0","v4.4.0","v4.3.0","v4.2.1","v4.2.0","v4.1.0","v4.0.1","v4.0.0","v3.13.0","v3.12.0","v3.11.1","v3.11.0","v3.10.0","v3.9.0","v3.8.2","v3.8.1","v3.8.0","v3.7.0","v3.6.0","v3.5.2","v3.5.1","v3.5.0","v3.3.0","v3.2.1","v3.2.0","v3.1.1","v3.1.0","v3.0.0","v3.0.0-beta.3","v3.0.0-beta.2","v3.0.0-beta.1","v2.8.0","v2.7.0","v2.6.2","v2.6.1","v2.6.0","v2.5.1","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.0","v2.0.0-rc.2","v2.0.0-rc.1","v1.21.1","v1.21.0","v1.20.2","v1.20.1","v1.20.0","v1.19.1","v1.19.0","v1.18.1","v1.18.0","v1.17.2","v1.17.1","v1.17.0","v1.16.2","v1.16.1","v1.16.0","v1.15.0","v1.14.2","v1.14.1","v1.14.0","v1.13.0","v1.11.1","v1.11.0","v1.10.0","v1.9.3","v1.9.2","v1.9.1","v1.9.0","v1.8.1","v1.8.0","v1.7.1","v1.7.0","v1.6.2","v1.6.1","v1.6.0","v1.5.3","v1.5.1","v1.5.0","v1.4.0","v1.3.1","v1.3.0","v1.2.0","v1.1.1","v1.1.0","v1.0.0","v1.0.0-beta.13","v1.0.0-beta.11","v1.0.0-beta.10","v1.0.0-beta.9.3","v1.0.0-beta.9.2","v1.0.0-beta.9.1","v1.0.0-beta.9","v1.0.0-beta.8.1","v1.0.0-beta.8","v1.0.0-beta.7","v1.0.0-beta.6","v1.0.0-beta.5.6","v1.0.0-beta.5.5","v1.0.0-beta.5.4","v1.0.0-beta.5.2","v1.0.0-beta.5.1","v1.0.0-beta.5","v1.0.0-beta.4.2","v1.0.0-beta.4.1","v1.0.0-beta.4","v1.0.0-beta.3","v1.0.0-beta.2.3","v1.0.0-beta.2.2","v1.0.0-beta.2.1","v1.0.0-beta.2","v1.0.0-beta.1.1","v1.0.0-beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61743.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
