CVE-2026-49942

Net::CIDR::Set versions through 0.20 for Perl did not validate network masks. The mask portion of a network mask could contain Unicode digits such as the Arabic-Indic One U+0661, or non-digits, which were ignored. This could allow network masks to accept larger networks. Leading zeros were also...

CVE-2026-49940

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...

CVE-2026-49941

CVE-2026-49941 affects Net::CIDR::Set (Perl) up to version 0.20. The vulnerability arises when add() delegates to _encode() to parse addresses; inputs that aren’t netmasks/ranges are treated as single IPs and recursed as 32/128-bit netmasks. If an argument isn’t a well-formed IP address, this can...

CVE-2026-49941

Net::CIDR::Set versions through 0.20 for Perl did not validate IP addresses. The add method called the encode method to parse addresses. If the addresses did not look like netmasks or network ranges, then they were assumed to single IP addresses and passed back to itself as a 32-bit or 128-bit...

CVE-2026-49940

Net::CIDR::Set for Perl is affected up to version 0.20. The issue arises because non-ASCII IP addresses and netmasks are accepted, with Unicode digits (e.g., Arabic-Indic One U+0661) not parsed as numbers, potentially allowing larger networks than intended. Several connected sources cite upgradin...
