Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-gv8p-48fr-4fxg plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 366,848 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
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) correctly blocks this, but the Sync API bypasses the controller-level check by writing directly through the DAL EntityWriter. The integration entity definition lacks WriteProtection, and the admin field has no field-level restriction flag.
OWASP: A01:2021 — Broken Access Control
Root Cause
IntegrationController::upsertIntegration() checks $source->isAdmin() before allowing the admin field to be set. However, SyncController::sync() routes writes through SyncService → EntityWriter, which only applies:
AclWriteValidator— checks entity-level ACL (integration:createis sufficient)EntityProtectionValidator— checksWriteProtectionon entity definitions, butIntegrationDefinitionhas none
The admin field in IntegrationDefinition is a plain BoolField with no WriteProtection or special flag. The Sync API writes it without restriction.
Vulnerable code path:
src/Core/Framework/Api/Controller/SyncController.php→SyncService→EntityWriter::upsert()- Missing protection:
src/Core/Framework/Integration/IntegrationDefinition.php—adminfield has noWriteProtection(Context::SYSTEM_SCOPE)
Working protection (bypassed):
src/Core/Framework/Integration/IntegrationController.php:46-56—isAdmin()check only applies to the dedicated controller endpoint
Impact
- Complete admin API access — the escalated integration has full read/write on every entity: users, customers, orders, system configuration, integrations, plugins
- PII exfiltration — read all customer records (names, emails, addresses, order history)
- Persistent backdoor — the admin integration survives password changes and user deactivation
Remediation
Add WriteProtection(Context::SYSTEM_SCOPE) to IntegrationDefinition, matching how UserDefinition and AclRoleDefinition are already protected:
// src/Core/Framework/Integration/IntegrationDefinition.php
(new BoolField('admin', 'admin'))
->addFlags(new WriteProtection(Context::SYSTEM_SCOPE)),

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for shopware/platform. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update shopware/platform to 6.7.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gv8p-48fr-4fxg is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-gv8p-48fr-4fxg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-gv8p-48fr-4fxg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-gv8p-48fr-4fxg in your dependencies?
O3 detects GHSA-gv8p-48fr-4fxg across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
