Title

Unrestricted Java Deserialization in OpenSearch SQL Plugin Cursor Pagination

Summary

Unrestricted deserialization of untrusted data in the cursor pagination component in the OpenSearch SQL plugin allows a remote authenticated user with basic read/search permissions to execute arbitrary code on the server by sending a crafted cursor parameter to the plugins/sql endpoint.
