From 3.3.0 until 3.9.2, enabling the global showURL setting causes the unauthenticated GET /api/v1/status-page/:url endpoint to return complete monitor objects from server/src/controllers/statusPageController.ts. The response includes the secret field used by HttpProvider.ts as an HTTP Authorization credential, even though BaseStatusPage.tsx does not display that value, allowing visitors to extract credentials from the JSON response and use them against monitored services. This issue is fixed in version 3.9.2.","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","CWE-522"],"references":["https://github.com/bluewave-labs/Checkmate/commit/cc1814f507041bb0f64845bed5d5442c21e920f2","https://github.com/bluewave-labs/Checkmate/pull/3758","https://github.com/bluewave-labs/Checkmate/releases/tag/v3.9.2","https://github.com/bluewave-labs/Checkmate/security/advisories/GHSA-3m74-8cg9-rp8j"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-71862","score":0.00482,"percentile":0.41247,"date":"2026-10-25"},"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).
