CVE-2026-14265
Bulletin ID: 2026-051-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/01/2026 12:45 PM PDT Description: The AWS Advanced JDBC Wrapper is an open-source JDBC driver wrapper that extends a JDBC driver to enable Amazon Aurora and AWS Cloud features such as failover handling and caching. We identified CVE-2026-14265, an issue in the RemoteQueryCachePlugin of the AWS Advanced JDBC Wrapper. When this plugin is enabled, query results read from the shared Redis/Valkey cache are deserialized without class filtering. An actor with write access to the shared cache infrastructure could insert a crafted serialized Java object that, when read by an application, results in execution of arbitrary code on the application server. Impacted versions: >=3.3.0 AND <=4.0.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
