# CVE-2026-107443: Red Hat Satellite information disclosure in foreman host template API

Affects Red Hat Satellite 6.16 (RHEL 8 and RHEL 9), 6.17 (RHEL 9) and 6.18 (RHEL 9), where host provisioning templates render secrets such as the host root password via root_pass.

- Severity: CVSS 7.7 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

CVE-2026-107443 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 7.7 (high) and affects Red Hat Satellite 6.16 for RHEL 8, Red Hat Satellite 6.16 for RHEL 9, Red Hat Satellite 6.17 for RHEL 9 and 1 more; no fixed version is listed; see the vendor advisory.

## Summary

Red Hat Satellite 6's foreman package has a flaw that lets a remote attacker with a low-privilege logon and view_hosts rights retrieve rendered provisioning template content for a host through the hosts template API endpoint. This can expose sensitive data such as a host's root password, and it is an incomplete fix for CVE-2026-96659.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Who should check

Teams running Red Hat Satellite 6.16 (RHEL 8 and 9) or 6.17 (RHEL 9) where users hold the view_hosts permission

## Description

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.

## What to do

- Check your stack: if you ship or depend on foreman, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, run the stack.check operation (execute) on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-107443 (Foreman: foreman: api host template render discloses secrets to view_hosts users (incomplete cve-2026-96659 fix)), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-107443 (entry last updated 2026-11-13):
Affected:
- Red Hat Red Hat Satellite 6.16 for RHEL 8: version range not reported
- Red Hat Red Hat Satellite 6.16 for RHEL 9: version range not reported
- Red Hat Red Hat Satellite 6.17 for RHEL 9: version range not reported
- Red Hat Red Hat Satellite 6.18 for RHEL 9: version range not reported
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Host provisioning template renders secrets, such as the host root password via the root_pass helper (source: https://bugzilla.redhat.com/show_bug.cgi?id=2547760)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, low-privilege login, no user action.
Workaround: Remove view_hosts from untrusted users or block/restrict GET /api/v2/hosts/:id/template/:kind until a fix is deployed. (source: https://access.redhat.com/errata/RHSA-2026:99949)
CISA KEV: CVE-2026-107443 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-107443 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

## FAQ

### Is CVE-2026-107443 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-107443

### What does this mean?

Users with the view_hosts permission can request a host's provisioning template through the API and see secrets rendered into it, including the host root password via the root_pass helper. This is an incomplete fix for CVE-2026-96659.

Source: https://bugzilla.redhat.com/show_bug.cgi?id=2547760, https://access.redhat.com/errata/RHSA-2026:99949

### Am I affected, and how do I check?

Red Hat Satellite 6.16 for RHEL 8 and RHEL 9, 6.17 for RHEL 9, and 6.18 for RHEL 9 are listed, and the advisory gives no version ranges. Exposure depends on which users hold view_hosts and on whether templates render secrets, so check your Satellite version and the roles assigned to users.

### How do I fix CVE-2026-107443?

The checked facts name no fixed version and no patch identifiers, so no upgrade target is given here. Follow the Red Hat advisory for a fix.

Source: https://bugzilla.redhat.com/show_bug.cgi?id=2547760, https://access.redhat.com/errata/RHSA-2026:99949

### What if there's no patch?

Remove view_hosts from untrusted users, or block or restrict GET /api/v2/hosts/:id/template/:kind until a fix is deployed.
