Privilege Escalation in AWS Advanced JDBC Wrapper GlobalDatabasePlugin for Amazon Aurora PostgreSQL
CVE-2026-11400 is an untrusted search path vulnerability in the GlobalDatabasePlugin component of the AWS Advanced JDBC Wrapper for Amazon Aurora PostgreSQL. According to the provided advisory text, a remote authenticated low-privilege actor can create a crafted function that is later executed when another Amazon RDS user connects to the cluster through an affected wrapper. Because the plugin resolves or invokes functionality in a way that permits attacker-controlled search path influence, the attacker can cause their crafted function to run in the context of the connecting user. This can result in privilege escalation from a low-privilege account to the privileges of another Amazon RDS user, including the rds_superuser role.
