MEDIUMPimcore Customer Data Framework Improper Access Control allows unprivileged user to access GDPR extracts
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.

Description
Summary
An authenticated and unauthorized user can access the GDPR data extraction feature and query over the information returned, leading to customer data exposure.
Details
Permissions do not seem to be 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. It seems that the access control is not enforced in this place : https://github.com/pimcore/customer-data-framework/blob/b4af625ef327c58d05ef7cdf145fa749d2d4195e/src/Controller/Admin/GDPRDataController.php#L38
PoC
In order to reproduce the issue, the following steps can be followed:
- As an administrator : a. Create a role without any permission through Settings → User & Roles → Roles in the administration panel b. Create an user through Settings → User & Roles → Users and assign it the unprivileged role previously created
- Log out the current administrator and log in with this new user
- Access to the following endpoint
https://pimcore_instance/admin/customermanagementframework/gdpr-data/search-data-objects?id=&firstname=&lastname=&email=&page=1&start=0&limit=50and the results will be returned to this unauthorized user.
Impact
An unauthorized user can access PII data from customers without being authorized to.

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 GHSA-g273-wppx-82w4 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-g273-wppx-82w4 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-g273-wppx-82w4. 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-g273-wppx-82w4 in your dependencies?
O3 detects GHSA-g273-wppx-82w4 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
