Description
Advisory title: Field-level security issue with .keyword fields
Affected versions:
OpenSearch 1.0.0-1.3.7 and 2.0.0-2.4.1
Patched versions:
OpenSearch 1.3.8 and 2.5.0
Impact:
There is an issue in the implementation of field-level security (FLS) and field masking where rules written to explicitly exclude fields are not correctly applied for certain queries that rely on their auto-generated .keyword fields.
This issue is only present for authenticated users with read access to the indexes containing the restricted fields.
Workaround:
FLS rules that use explicit exclusions can be written to grant explicit access instead. Policies authored in this way are not subject to this issue.
Patches:
OpenSearch versions 1.3.8 and 2.5.0 contain a fix for this issue.

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-security. 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-security to 1.3.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v3cg-7r9h-r2g6 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-v3cg-7r9h-r2g6 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-v3cg-7r9h-r2g6. 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-v3cg-7r9h-r2g6 in your dependencies?
O3 detects GHSA-v3cg-7r9h-r2g6 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
