How to fix?

Upgrade redis to version 4.4.4, 4.5.4 or higher.

Overview

Affected versions of this package are vulnerable to Exposure of Data Element to Wrong Session due to a race condition when a queued connection is left open after canceling an async Redis command involving a non pipelined operation, at an inopportune time. The server can send response data to the client of an unrelated request in an off-by-one manner.

NOTE: this issue exists because of an incomplete fix for CVE-2023-28858.
