In RestEasy Reactive implementation of Quarkus the insecure File.createTempFile() is used in the FileBodyHandler class which creates temp files with insecure permissions that could be read by a local user.
Opening temporary files without appropriate measures or controls can leave the file, its contents and any function that it impacts vulnerable to attack.
