SUSE CVE-2025-40911

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...

SUSE 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...

SUSE 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-2026-45191

A flaw was found in Net::CIDR::Lite. This vulnerability allows an attacker to bypass IP Access Control Lists ACLs by providing specially crafted CIDR Classless Inter-Domain Routing mask values. The component incorrectly processes mask forms containing extraneous zero characters, such as "/00" or...

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-2026-49941

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-2026-49940

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...
