CVE-2025-9572 Overview
An authorization flaw in Foreman's GraphQL API allows low-privileged users to access metadata beyond their assigned permissions. Unlike the REST API, which correctly enforces access controls, the GraphQL endpoint does not apply proper filtering, leading to an authorization bypass. This vulnerability represents a significant gap in access control implementation where the GraphQL API fails to enforce the same permission checks that are properly implemented in the REST API.
Critical Impact
Low-privileged authenticated users can bypass authorization controls to access sensitive metadata through the GraphQL API endpoint, potentially exposing confidential system information.
Affected Products
- Foreman (versions with GraphQL API enabled)
- Red Hat Satellite (as referenced in RHSA advisories)
- Red Hat products using Foreman components

Technical Details for CVE-2025-9572
Vulnerability Analysis
This vulnerability stems from inconsistent authorization enforcement between Foreman's two API implementations. While the REST API properly validates user permissions before returning data, the GraphQL API fails to apply equivalent access control filters. This discrepancy allows authenticated users with limited privileges to query and retrieve metadata that should be restricted based on their role assignments.
The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), indicating that the flaw results in information disclosure to users who should not have access to specific data. The network-accessible nature of this vulnerability means any authenticated user with network access to the Foreman GraphQL endpoint can potentially exploit this weakness.
Root Cause
The root cause lies in the authorization layer implementation within Foreman's GraphQL API. When processing GraphQL queries, the application fails to apply the same permission-based filtering logic that exists in the REST API. This creates an authorization bypass where the GraphQL resolvers return data without verifying whether the requesting user has appropriate permissions to access the queried resources.
Attack Vector
The attack vector requires network access and low-privilege authentication. An attacker must first obtain valid credentials to access the Foreman system, even with minimal permissions. Once authenticated, they can craft GraphQL queries targeting metadata resources that would normally be restricted. The GraphQL endpoint processes these queries without proper authorization checks, returning data that the user's assigned role should not permit access to.
The vulnerability can be exploited by sending carefully constructed GraphQL queries to the API endpoint. An attacker would enumerate available fields and types through GraphQL introspection, then query for sensitive metadata such as host configurations, organizational structures, or system parameters that exceed their authorized scope. For technical exploitation details, refer to the Foreman Security Advisory and Red Hat Bug Report #2391715.
Detection Methods for CVE-2025-9572
Indicators of Compromise
- Unusual GraphQL query patterns from low-privileged user accounts attempting to access administrative metadata
- Increased volume of GraphQL API requests compared to baseline activity, particularly introspection queries
- Authentication logs showing users querying resources outside their typical operational scope
- GraphQL query logs containing requests for sensitive metadata fields by unauthorized accounts
Detection Strategies
- Implement logging for all GraphQL API requests with user identity correlation to identify permission boundary violations
- Monitor for GraphQL introspection queries which may indicate reconnaissance activity preceding exploitation
- Compare user permission levels against resources accessed through GraphQL queries to detect authorization bypasses
- Deploy API anomaly detection to identify unusual query patterns or data access requests
Monitoring Recommendations
- Enable detailed audit logging on Foreman GraphQL endpoints to capture query content and user context
- Establish baseline GraphQL usage patterns per user role to facilitate deviation detection
- Configure alerts for GraphQL queries accessing metadata types that don't align with the requesting user's assigned permissions
- Review GraphQL query logs regularly for signs of enumeration or unauthorized data access attempts
How to Mitigate CVE-2025-9572
Immediate Actions Required
- Apply the security patches referenced in Red Hat Security Advisories RHSA-2025:21886, RHSA-2025:21893, RHSA-2025:21894, and RHSA-2025:21897
- Review and audit user accounts with GraphQL API access to ensure principle of least privilege
- Consider temporarily disabling GraphQL API access if not operationally required until patches are applied
- Implement network-level restrictions to limit GraphQL endpoint access to trusted sources
Patch Information
Security patches addressing this authorization bypass are available through the following Red Hat Security Advisories:
- RHSA-2025:21886 - Red Hat Security Advisory
- RHSA-2025:21893 - Red Hat Security Advisory
- RHSA-2025:21894 - Red Hat Security Advisory
- RHSA-2025:21897 - Red Hat Security Advisory
Additional details can be found in the Foreman Security Update and the Red Hat CVE Record.
Workarounds
- Disable GraphQL API access entirely if the functionality is not required for operations
- Implement network segmentation to restrict GraphQL endpoint access to administrative networks only
- Use reverse proxy or API gateway rules to block GraphQL queries from users without explicit authorization
- Monitor and audit all GraphQL API activity until patches can be applied to production systems
# Example: Restrict GraphQL endpoint access via Apache configuration
# Add to Foreman Apache configuration to limit GraphQL access
<Location /api/graphql>
Require group foreman-admins
# Or restrict by IP range
# Require ip 10.0.0.0/8 192.168.0.0/16
