Cpan

CPAN hosts a modestly represented collection of open-source Perl modules that, despite a narrow product scope, reach into diverse downstream applications and build pipelines where Perl remains embedded. The vulnerabilities affecting this repository skew toward serious outcomes, clustering around file-handling and command-injection weaknesses—link-following flaws and improper neutralization of shell metacharacters—that are characteristic of scripting-language libraries where input validation and file-access boundaries require careful implementation. Defenders should inventory Perl dependencies in their supply chains and treat updates to widely used CPAN modules as components requiring review; current severity, exploitation, and coverage details are shown alongside this summary.
