## Technical details

The vulnerability is a missing authorization check (CWE-862) in phpIPAM's customer, location, and NAT detail pages, which fail to call Subnets::check_permission before displaying subnet information. An authenticated attacker with low privileges can directly access objects.php, single-location.php, or nat_details.php to read restricted IP address data. The fix requires adding proper permission validation to these pages before rendering sensitive data.
