7.7 highEPSS 0.5%Fix available

High (7.7) in red hat. EPSS 0.5% estimated probability of exploitation activity in the next 30 days.

On this page
A flaw was found in Foreman. An authenticated user with view_hosts privileges can retrieve rendered provisioning template content for a host via the hosts template API endpoint, disclosing sensitive data such as the host root password. This is an incomplete fix of CVE-2026-96659, which hardened the web UI preview path but left the API host-template render path authorized for Viewer-level users.

Red Hat's mitigation

Until a fix is deployed, remove view_hosts from untrusted users or block/restrict GET /api/v2/hosts/:id/template/:kind. Prefer granting only trusted administrators access that can view host provisioning output. Rotate host root credentials if Viewer-role users may have accessed this endpoint.
