CVE-2026-11400 is an untrusted search path vulnerability in the GlobalDatabasePlugin of the AWS Advanced JDBC Wrapper for Amazon Aurora PostgreSQL. This flaw allows a remote authenticated low-privilege user to escalate privileges to those of another Amazon RDS user, including the highly privileged rds_superuser role, by creating a crafted function that executes upon connection through the affected wrapper. The issue affects versions from 3.0.0 up to but not including 4.0.1. AWS has released version 4.0.1 to remediate this vulnerability.
