Bug #133214 for CPAN: cpan lists entries unrelated to Perl (including restricted entries) at least on OSX systems

Greetings, I have observed a weird behaviour of the cpan (not cpanm) command on a MacOSX system (my exact version is 10.15.3, but I think it should be easily reproducible with any recent enough OSX system). When I want to list the Perl modules installed by cpan on my system, the loop ends up trying to access Pictures and other System folders unrelated to Perl. The OS informs me (by a popup window) that the application is trying to access restricted folders, and here is what happens when I dutifully refuse (I colorized the output for clarity). Not sure if this bug is already known or reported, but I don’t think it’s the intended behaviour for such a ubiquitous (and still extremely useful) tool.
