CVE-2024-39676
HIGHCVE-2024-39676 is a high-severity (CVSS 7.5) Information Exposure vulnerability in org.apache.pinot:pinot-controller. O3 Security confirms whether CVE-2024-39676 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apache Pinot: Unauthorized endpoint exposed sensitive information
Real-World Exposure
org.apache.pinot:pinot-controllerReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Pinot.
This issue affects Apache Pinot: from 0.1 before 1.0.0.
Users are recommended to upgrade to version 1.0.0 and configure RBAC, which fixes the issue.
Details:
When using a request to path “/appconfigs” to the controller, it can lead to the disclosure of sensitive information such as system information (e.g. arch, os version), environment information (e.g. maxHeapSize) and Pinot configurations (e.g. zookeeper path). This issue was addressed by the Role-based Access Control https://docs.pinot.apache.org/operators/tutorials/authentication/basic-auth-access-control , so that /appConfigs` and all other APIs can be access controlled. Only authorized users have access to it. Note the user needs to add the admin role accordingly to the RBAC guide to control access to this endpoint, and in the future version of Pinot, a default admin role is planned to be added.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.pinot:pinot-controller. 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 org.apache.pinot:pinot-controller to 1.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-39676 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-2024-39676 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-2024-39676. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-39676 in your dependencies?
O3 detects CVE-2024-39676 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
