{"id":"DEBIAN-CVE-2026-45190","details":"Net::CIDR::Lite versions before 0.24 for Perl does not properly validate IP address and CIDR mask inputs, which may allow IP ACL bypass.  Inputs containing a trailing newline or non-ASCII digit characters pass the validators but are then re-encoded by the parser to a different address than the input string spelled. find() and bin_find() can match or miss addresses as a result.  Example:    my $cidr = Net::CIDR::Lite-\u003enew();   $cidr-\u003eadd(\"::1\\n/128\");   $cidr-\u003efind(\"::1a\");  # incorrectly returns true  See also CVE-2026-45191.","modified":"2026-09-14T17:03:13.479859321Z","published":"2026-05-10T21:16:29.273Z","upstream":["CVE-2026-45190"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-45190"}],"affected":[{"package":{"name":"libnet-cidr-lite-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libnet-cidr-lite-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.22-3~deb12u2"}]}],"versions":["0.22-2","0.22-3~deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-45190.json"}},{"package":{"name":"libnet-cidr-lite-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libnet-cidr-lite-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.22-3~deb13u2"}]}],"versions":["0.22-2","0.22-3~deb12u1","0.22-3~deb12u2","0.22-3~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-45190.json"}},{"package":{"name":"libnet-cidr-lite-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libnet-cidr-lite-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.24-1"}]}],"versions":["0.22-2","0.22-3","0.22-3~deb12u1","0.22-3~deb12u2","0.22-3~deb13u1","0.22-3~deb13u2","0.23-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-45190.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}
