Upstream information

CVE-2026-45190 at MITRE

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
