CVE-2026-108720
phpIPAM through 1.8.3 contains a missing authorization vulnerability that allows authenticated low-privilege users to view restricted subnets and addresses because customer, location and NAT pages skip Subnets::check_permission.
Does this matter?
Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.
Description
phpIPAM through 1.8.3 contains a missing authorization vulnerability that allows authenticated low-privilege users to view restricted subnets and addresses because customer, location and NAT pages skip Subnets::check_permission. Attackers can open customer objects.php, single-location.php or nat_details.php to read IP addresses, CIDRs, hostnames and MAC addresses from sections they cannot access.
