CVE-2026-18061 - XML External Entity (XXE) in AWS Advanced JDBC Wrapper RemoteQueryCachePlugin
Bulletin ID: 2026-109-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 09/11/2026 09:30 AM PDT Description: The AWS Advanced JDBC Wrapper is an open-source library that enhances existing JDBC drivers with AWS-specific capabilities such as Aurora failover, IAM authentication, and automated SQL query caching for applications connecting to Amazon Aurora, RDS MySQL, and RDS MariaDB. We identified CVE-2026-18061, an improper restriction of XML external entity (XXE) references in the optional RemoteQueryCachePlugin. When this plugin is enabled with a shared cache, an actor with write access to that cache infrastructure might place crafted XML in a cached column value. When an application subsequently reads that cached result as XML, the wrapper's XML parsers resolve external entities, which might allow the actor to disclose sensitive files readable by the application process, including stored database and IAM role credentials. Impacted versions: >= 3.3.0 and <= 4.2.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
