CVE-2026-45190
Description
AI Translation Available
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
