    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
    CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
