CVE-2026-48008 in Shopware
Summary
by MITRE • 07/17/2026
Shopware is an open commerce platform. Prior to 6.6.10.18 and 6.7.10.1, a non-admin API user with integration:create ACL privilege can escalate to full administrator by creating an integration with admin: true through the Sync API POST /api/_action/sync; the regular integration endpoint POST /api/integration blocks this, but SyncController::sync() routes writes through SyncService to EntityWriter::upsert(), and src/Core/Framework/Integration/IntegrationDefinition.php lacks WriteProtection on the admin field. This issue is fixed in versions 6.6.10.18 and 6.7.10.1.

This vulnerability represents a critical privilege escalation flaw in Shopware commerce platforms affecting versions prior to 6.6.10.18 and 6.7.10.1. The issue stems from an inconsistent access control implementation within the platform's integration management system, specifically exploiting a gap between different API endpoints that handle integration creation. A non-admin user with the specific integration:create ACL privilege can leverage this vulnerability to gain full administrative rights through a carefully crafted API request.
The technical exploitation occurs through the Sync API endpoint POST /api/_action/sync which functions differently from the standard integration endpoint POST /api/integration. While the regular integration endpoint properly validates and blocks attempts to create integrations with admin: true, the sync endpoint's implementation bypasses these protections by routing writes through the SyncService to EntityWriter::upsert() method. This architectural inconsistency creates a vector for privilege escalation because the underlying IntegrationDefinition.php file lacks proper WriteProtection on the admin field, allowing unauthorized modification of this critical permission flag during bulk operations.
The operational impact of this vulnerability is severe as it allows attackers with relatively low-level privileges to completely compromise system security and gain unrestricted access to all administrative functions. This includes but is not limited to user management, order processing, product catalog manipulation, payment configuration changes, and access to sensitive customer data. The vulnerability essentially provides a backdoor for attackers to elevate their privileges without requiring additional authentication credentials or more sophisticated attack vectors.
This issue maps directly to CWE-284 (Improper Access Control) and aligns with ATT&CK technique T1078 (Valid Accounts) and T1548.003 (Sudo and SUID). The vulnerability demonstrates poor defense-in-depth principles where access controls are not consistently enforced across different API endpoints, creating multiple paths for privilege escalation. The fix implemented in versions 6.6.10.18 and 6.7.10.1 addresses the root cause by properly enforcing WriteProtection on the admin field within IntegrationDefinition.php and ensuring consistent validation behavior across all integration creation pathways.
Security practitioners should immediately apply the patched versions to mitigate this risk, while also implementing monitoring for unusual integration creation patterns and administrative privilege changes within their Shopware environments. Organizations should conduct thorough access control reviews to identify similar inconsistencies in other API endpoints that might present comparable vulnerabilities. The incident highlights the importance of maintaining consistent security controls across all application interfaces and demonstrates how seemingly minor implementation differences can create significant security risks.
Additional mitigations include implementing network-level restrictions on sensitive API endpoints, enabling detailed logging of integration management activities, and conducting regular security assessments of custom integration workflows that might leverage similar patterns. Organizations should also consider implementing role-based access control reviews to ensure that users with integration:create privileges cannot inadvertently gain administrative capabilities through legitimate business processes. The vulnerability serves as a reminder that API endpoint consistency is crucial for maintaining effective access controls and preventing privilege escalation attacks.
