How to fix?

Upgrade io.netty:netty-common to version 4.1.77.Final or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure due to an incomplete fix to CVE-2021-21290, which still allowed one exploitable path. When netty's multipart decoders are used, local information disclosure can occur via the local system temporary directory, if temporary storing uploads on the disk is enabled. Note: To be vulnerable, a victim application has to run on a Unix-like operating system, and with Java 6 or below.
