## Overview

Improper restriction of XML external entity references in the RemoteQueryCachePlugin in AWS Advanced JDBC Wrapper 3.3.0 through 4.2.0 might allow an actor with write access to the shared cache infrastructure to disclose sensitive files from application hosts that read cached query results, including stored database and IAM role credentials, via crafted XML data in a cached column value.



To remediate this issue, users should upgrade to version 4.3.0 or later.

## Affected

- `advanced_jdbc_wrapper >= 3.3.0, < 4.3.0`
