Prior to 0.24.2, GET /api/namespaces/:tenant returns the full namespace object — including\nthe members list (user IDs, e-mails, roles), settings, and device counts — to any caller authenticated by an API Key, for any tenant, regardless of the API Key's own tenant scope. The handler conditionally skips the membership check when the user ID (X-ID) is absent, which is exactly the case for API Key authentication. This vulnerability is fixed in 0.24.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-639"],"references":["https://github.com/shellhub-io/shellhub/security/advisories/GHSA-vwx9-7qcf-gg7f","https://github.com/shellhub-io/shellhub/security/advisories/GHSA-vwx9-7qcf-gg7f"],"products":["shellhub:shellhub"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-44426","score":0.00308,"percentile":0.23612,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-vwx9-7qcf-gg7f","url":"https://osv.dev/vulnerability/GHSA-vwx9-7qcf-gg7f","summary":"ShellHub has cross-tenant IDOR in `GET /api/namespaces/:tenant` via API Key bypasses  membership check","modified":"2026-06-25T23:11:32.461990375Z","packages":[{"ecosystem":"Go","name":"github.com/shellhub-io/shellhub","purl":"pkg:golang/github.com/shellhub-io/shellhub","ranges":["<0.24.2"],"fixed":["0.24.2"]}]},{"id":"GO-2026-5680","url":"https://osv.dev/vulnerability/GO-2026-5680","summary":"ShellHub has cross-tenant IDOR in `GET /api/namespaces/:tenant` via API Key bypasses membership check in github.com/shellhub-io/shellhub","modified":"2026-06-25T23:01:25.595497428Z","packages":[{"ecosystem":"Go","name":"github.com/shellhub-io/shellhub","purl":"pkg:golang/github.com/shellhub-io/shellhub","ranges":["<0.24.2"],"fixed":["0.24.2"]}]}],"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).
