MEDIUMCVE-2024-21667 is a medium-severity (CVSS 6.5) CWE-284 vulnerability in pimcore/customer-management-framework-bundle. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2024-21667 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Pimcore Customer Data Framework Improper Access Control allows unprivileged user to access GDPR extracts
Blast Radius
pimcore/customer-management-framework-bundleReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
pimcore/customer-data-framework is the Customer Management Framework for management of customer data within Pimcore. An authenticated and unauthorized user can access the GDPR data extraction feature and query over the information returned, leading to customer data exposure. Permissions are not enforced when reaching the /admin/customermanagementframework/gdpr-data/search-data-objects endpoint allowing an authenticated user without the permissions to access the endpoint and query the data available there. An unauthorized user can access PII data from customers. This vulnerability has been patched in version 4.0.6.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pimcore/customer-management-framework-bundle. 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 pimcore/customer-management-framework-bundle to 4.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-21667 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 CVE-2024-21667 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 CVE-2024-21667. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
