CVE-2023-28858  (opens in a new tab)
CWE-488  (opens in a new tab)

How to fix?

Upgrade redis to version 4.3.6, 4.4.3, 4.5.3 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 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: The same vulnerability exists for non-pipelined operations, which was discovered after this one and is addressed by CVE-2023-28859.
