Description
A flaw was found in Redis. An authenticated attacker, in an unusual configuration where they can execute the RESTORE command, could exploit a double free vulnerability. This occurs when a specially crafted RESTORE payload references the same NACK (pending entry) by multiple consumers, and both consumers are subsequently deleted via XGROUP DELCONSUMER. Successful exploitation of this flaw could lead to remote code execution.
