CVE ID :CVE-2026-45190
Published : May 10, 2026, 9:16 p.m. | 1 hour, 13 minutes ago
Description :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
