Description
OpenSearch Observability is collection of plugins and applications that visualize data-driven events. An issue in the OpenSearch observability plugins allows unintended access to private tenant resources like notebooks. The system did not properly check if the user was the resource author when accessing resources in a private tenant, leading to potential data being revealed. The patches are included in OpenSearch 2.14.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.opensearch.plugin:opensearch-observability. 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.opensearch.plugin:opensearch-observability to 2.14.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-39901 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-2024-39901 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-2024-39901. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
