Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- 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
CVE-2024-39676 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 378,567 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
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-39676 can be triaged on real exposure rather than presence alone.
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 Security finds CVE-2024-39676 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
