CVE-2026-96659

Foreman: excessive permissions for viewer role on preview

Published Oct 1, 2026 CVSS 3.1 · 9.1 Critical EPSS < 1% KEV · Not listed
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.

Analysis

AI-generated

Technical impact

A flaw in Foreman allows an authenticated user with the low‑level Viewer role to submit requests to template preview endpoints, resulting in the disclosure of sensitive information such as host root passwords. Under insecure system configurations where Safemode protections are disabled, the same flaw can enable the user to execute arbitrary commands as the Foreman system account. The weakness derives from improper access control (CWE‑267).

Affected Systems

The vulnerability affects Red Hat Satellite 6.19 for RHEL 9, specifically the Satellite, Capsule, and Utils components identified by the product name Red Hat Satellite and the version 6.19. No other versions have been reported as impacted.

Risk and Exploitability

The CVSS score of 9.1 indicates a high severity, and the EPSS score is currently unavailable so the exact likelihood of exploitation in the wild is unknown. The flaw is not listed in the CISA KEV catalog, but the high severity and the ability to gain detailed system information or elevate privileges make it a high risk if an authenticated user is able to access preview endpoints. Exploitation requires an authenticated session; therefore the attack vector is primarily the web API or UI of Foreman, not a remote network attack without authentication.

Remediation

Vendor Workaround

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Keeping the Foreman Safemode protection enabled (the default configuration) limits the risk of remote code execution via this flaw, but does not prevent the underlying information disclosure. Updated foreman packages addressing this issue are delivered through Red Hat Satellite errata; users should apply the relevant Satellite updates.


OpenCVE Recommended Actions

  • Apply the Red Hat erratum RHSA-2026:74503 that patches the flaw in the Satellite 6.19 components
  • Re‑enable or tighten Safemode protections to prevent arbitrary command execution from user input
  • Review and adjust the permissions granted to the Viewer role so that preview endpoints are not accessible by low‑privilege users
