Comment 1 Thomas Leroy 2021-12-16 11:13:34 UTC

I can't find signs of this module in perl5 source, or in other packages. I am actually not sure if we ship this cpan package.

Comment 2 Thomas Leroy 2022-08-24 14:59:21 UTC

Michael, can you please help us to find if we're affected or not?

Comment 3 Michael Schröder 2022-08-29 13:49:03 UTC

I could not find the module in our products. It's used by the upstream CPAN server, so there's no need for us to ship it.

So I don't think we're affected.
