A double free error occurs when an authenticated attacker executes the RESTORE command. This happens when a RESTORE payload references the same NACK (pending entry) across multiple consumers, and both consumers are subsequently deleted using the
XGROUP DELCONSUMER function. This flaw can allow a remote attacker to execute arbitrary code.Recommendations
Update to version 8.8.0 or later.
