MEDIUMOpenSearch Observability does not properly restrict access to private tenant resources
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 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.
Impact
The lack of proper access control validation for private tenant resources in the OpenSearch observability and reporting plugins can lead to unintended data access. If an authorized user with observability or reporting roles is aware of another user's private tenant resource ID, such as a notebook, they can potentially read, modify, or take ownership of that resource, despite not being the original author, thus impacting the confidentiality and integrity of private tenant resources. The impact is confined to private tenant resources, where authorized users may gain inappropriate visibility into data intended to be private from other users within the same OpenSearch instance, potentially violating the intended separation of access. This issue does not alter the scope of access but highlights a flaw in the existing access control mechanisms.

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 GHSA-77vc-rj32-2r33 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-77vc-rj32-2r33 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-77vc-rj32-2r33. 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-77vc-rj32-2r33 in your dependencies?
O3 detects GHSA-77vc-rj32-2r33 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
