The send_stats method does not remove newlines from metric names ($stat variable), allowing attackers to change the metric name prefix.
The send_stats method does not validate the content of the value ($delta variable), allowing attackers to inject metrics, especially from methods that do not restrict the data type for the value, such as set, gauge, count and histogram.
The send_stats method does not validate the content of the tags, which may contain newlines, pipes and colons that allow metric injections.
Note that the SYNOPSIS shows an example of passing a website form "loginName" parameter as a tag, which is unsafe.
