Prior to version 0.3.4, the `/api/v1/*` route surface trusts the bearer token alone for authorisation on most endpoints. The codebase itself admits this at `internal/api/hosts.go:384`: \"API trusts the bearer token for authorisation; per-CA ownership is enforced only in the Web layer.\" The Web UI gates state-changing routes through `loadAccessibleCA` (`internal/web/cas.go`); CA-management endpoints in `internal/api/cas.go` ALSO have proper `canAccessCA` gates. The gap is on the host, network, firewall, mobile-bundle, and most operator endpoints. Combined with the per-operator CA model from ADR 0002, this gives any non-admin operator API key broad cross-tenant access — instant privilege escalation in the worst case. Version 0.3.4 fixes the issue.","state":0,"publishedAt":"2026-07-23T21:17:04.477+00:00","modifiedAt":"2026-10-24T13:10:00.147+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/forgekeep/nebula-mesh/commit/9d8bcd7667ecd0c2975cc71fb35a02fe131f76f2","https://github.com/forgekeep/nebula-mesh/security/advisories/GHSA-598g-h2vc-h5vg"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-47724","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-862"],"productCriteria":[],"sourceDates":{"published":"2026-07-23T21:17:04.477","lastModified":"2026-10-24T13:10:00.147"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
