CVE-2026-18061Network attack vectorHinoki check available

Application file disclosure via cached XML entities

Published Sep 11, 2026 · Updated Sep 11, 2026

XXE in AWS Advanced JDBC Wrapper RemoteQueryCachePlugin 3.3.0 through 4.2.0 allows remote authenticated users to read application-host files. CachedSQLXML passes cached XML to DOM, SAX, or StAX parsers without disabling DTD processing or external entity resolution, so crafted entities resolve local resources. Exploitation requires the non-default plugin, write access to shared Valkey cache, and an application that parses poisoned SQLXML; exposed files can include database and IAM credentials.
