Ricardo Signes reports:

Beginning in PathTools 3.47 and/or perl 5.20.0, the File::Spec::canonpath() routine returned untained strings even if passed tainted input. This defect undermines the guarantee of taint propagation, which is sometimes used to ensure that unvalidated user input does not reach sensitive code.

This defect was found and reported by David Golden of MongoDB.
