Description (CNA)
Net::CIDR::Lite versions before 0.24 for Perl does not properly validate IP address and CIDR mask inputs, which may allow IP ACL bypass. Inputs containing a trailing newline or non-ASCII digit characters pass the validators but are then re-encoded by the parser to a different address than the input string spelled. find() and bin_find() can match or miss addresses as a result. Example: my $cidr = Net::CIDR::Lite->new(); $cidr->add("::1\n/128"); $cidr->find("::1a"); # incorrectly returns true See also CVE-2026-45191.
