Publication date: 2026-11-12

Last updated on: 2026-11-12

Assigner: AMZN

Description
An untrusted search path issue in Aurora PostgreSQL dialect detection in the AWS Advanced Go Wrapper from release 2026-04-06 (awssql/v2.0.0) and before release 2026-07-29 (awssql/v2.0.3) could allow a remote authenticated user to escalate privileges to those of another database user, including a member of the rds_superuser role, via a crafted function that runs when that user connects to an Aurora PostgreSQL cluster through an affected version of the wrapper. To remediate this issue, users should upgrade to the AWS Advanced Go Wrapper release 2026-07-29 (awssql/v2.0.3) or later.

Executive Summary

This vulnerability is an untrusted search path issue in Aurora PostgreSQL dialect detection in the AWS Advanced Go Wrapper. It allows a remote authenticated user to escalate privileges to those of another database user, including rds_superuser, via a crafted function when connecting to an Aurora PostgreSQL cluster through an affected wrapper version.

Impact Analysis

An attacker with database access could exploit this to gain higher privileges, potentially accessing sensitive data or performing unauthorized actions. This includes escalating to rds_superuser role privileges, which could compromise the entire database cluster.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. Organizations using affected versions may face compliance violations, data breaches, and potential regulatory penalties.

Mitigation Strategies

Upgrade to AWS Advanced Go Wrapper release 2026-07-29 (awssql/v2.0.3) or later to patch the vulnerability.

If immediate upgrade is not possible, restrict CREATE permission on the public schema and other schemas in the search path to trusted users only.
