Of 381,682 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Counts from FIRST.org, log-scaled.
Description
A flaw was found in Foreman. This vulnerability allows an authenticated user with low-level Viewer permissions to cause unauthorized information disclosure by submitting requests to template preview endpoints. By exploiting this issue, the user can access sensitive data, such as host root passwords. Furthermore, under insecure system configurations where Safemode protections are disabled, the flaw may allow the user to execute arbitrary commands as the Foreman system account.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-96659 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This vulnerability is rated as having an Important security impact because authenticated users assigned restricted Viewer permissions can bypass role-based access controls to retrieve sensitive host credentials. In Red Hat Satellite environments, querying template preview endpoints exposes critical host attributes…
