Overview
Affected versions of this package are vulnerable to Double Free in the RESTORE process when the same NACK (pending entry) is referenced by more than one consumer. An attacker can achieve remote code execution by crafting a malicious RESTORE payload and deleting both consumers via the XGROUP DELCONSUMER command. This is only exploitable if an authenticated attacker can execute the RESTORE command and manipulate consumer groups in this specific manner.
