Hi,

The following vulnerability was published for libnet-cidr-set-perl.

CVE-2025-40911[0]:
| Net::CIDR::Set versions 0.10 through 0.13 for Perl does not properly
| handle leading zero characters in IP CIDR address strings, which
| could allow attackers to bypass access control that is based on IP
| addresses.  Leading zeros are used to indicate octal numbers, which
| can confuse users who are intentionally using octal notation, as
| well as users who believe they are using decimal notation.
| Net::CIDR::Set used code from Net::CIDR::Lite, which had a similar
| vulnerability CVE-2021-47154.


If you fix the vulnerability please also make sure to include the
