CVE-2026-49940 is fixed in libnet-cidr-set-perl on 1 platform, first by DEBIAN-CVE-2026-49940, released June 24, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Net::CIDR::Set versions through 0.20 for Perl accept non-ASCII IP addresses and netmasks. Unicode digits such as the Arabic-Indic One (U+0661) were accepted but not properly parsed as numbers. This could allow network masks to accept larger networks.
