CVE ID: CVE-2026-86287 Distribution: Net-IP-LPM Versions: before 1.12 MetaCPAN: https://metacpan.org/dist/Net-IP-LPM VCS Repo: https://github.com/robrwo/perl-Net-IP-LPM Net::IP::LPM versions before 1.12 for Perl accept malformed prefix lengths Description ----------- Net::IP::LPM versions before 1.12 for Perl accept malformed prefix lengths. Non-numeric and non-ASCII prefix lengths are accepted and treated as 0. Integers over 31 bits are silently truncated. A single malformed mask will poison the lookup table. The result is that the lookup will silently succeed for every address. An allow-list will allow every address, and a deny-list will block every address. Problem types ------------- - CWE-1287 Improper Validation of Specified Type of Input Solutions --------- Upgrade to Net::IP::LPM version 1.12 or later.
