  "details": "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-\u003enew();   $cidr-\u003eadd(\"::1\\n/128\");   $cidr-\u003efind(\"::1a\");  # incorrectly returns true  See also CVE-2026-45191.",
