An issue in AWS Wrappers for Amazon Aurora PostgreSQL may allow for privilege escalation to rds_superuser role. A low privilege authenticated user can create a crafted function that could be executed with permissions of other Amazon Relational Database Service (RDS) users.
We recommend customers upgrade to the following versions: AWS JDBC Wrapper to v2.6.5, AWS Go Wrapper to 2025-10-17, AWS NodeJS Wrapper to v2.0.1, AWS Python Wrapper to v1.4.0 and AWS PGSQL ODBC driver to v1.0.1
