CVE-2026-96659
CRITICAL 9.1A 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.
Severe if exploited (CVSS 9.1), but no known exploitation and low modeled probability. Patch on a normal cadence.
