Overview

Affected versions of this package are vulnerable to Unsafe Dependency Resolution in the COPY FROM STDIN process. An attacker can execute arbitrary commands by injecting specially crafted data lines when an early failure occurs before the server signals readiness for input rows. This is only exploitable if the attacker can control both the server and the data rows, or if an attacker controlling only the data rows can trigger a coincidental error.
