CVE-2024-57868
Web::API 2.8 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
Does this matter?
Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.
Description

Specifically Web::API uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
