CVE-2021-21290

In Netty there is a vulnerability on Unix-like systems involving an insecure temp file. When netty's multipart decoders are used, a local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. On unix-like systems, the temporary directory is shared between all user. As such, writing to this directory using APIs that do not explicitly set the file/directory permissions can lead to information disclosure.
