Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The AWS Advanced JDBC Wrapper (Maven software.amazon.jdbc:aws-advanced-jdbc-wrapper) versions 3.0.0 up to but not including 4.0.1 are affected. A low-privilege authenticated user can create a crafted function that runs with the permissions of other RDS users, allowing escalation to the rds_superuser role. Upgrade to version 4.0.1. As a workaround, remove the public schema from the search path.
