An authenticated user with host-edit permissions could exploit a cross-tenant information disclosure vulnerability. This flaw occurs because the taxonomy_scope controller method does not properly validate organization and location IDs from nested request parameters, bypassing existing authorization checks. This allows the user to leak sensitive infrastructure metadata, including subnet topology, IP ranges, gateways, DNS servers, and VLAN IDs, from organizations and locations they are not authorized to access.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-639"],"references":["https://access.redhat.com/errata/RHSA-2026:34365","https://access.redhat.com/errata/RHSA-2026:34366","https://access.redhat.com/errata/RHSA-2026:34367","https://access.redhat.com/errata/RHSA-2026:34368","https://access.redhat.com/security/cve/CVE-2026-5138"],"products":["redhat:satellite","theforeman:foreman"],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-5138","score":0.0038,"percentile":0.31996,"date":"2026-10-31"},"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).
