CPAN Security Group

Welcome to the CPAN Security Group. This is a community effort for supporting and responding to security incidents on CPAN – the Comprehensive Perl Archive Network.

This group also cares about security-related topics around CPAN distributions, the CPAN/PAUSE infrastructure, and about tooling and the ecosystem in general. Over time, we aim to improve supply chain security, make CPAN a more secure and trustworthy publishing platform, and more.
