Summary
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.
Risk Assessment
Authenticated low-privilege users can access network information they are not authorized to view, leading to confidentiality breaches. This may result in exposure of sensitive data about network infrastructure.
Recommendation
Update phpIPAM to a version later than 1.8.3 if available, or apply patches that enforce Subnets::check_permission on customer, location, and NAT pages. Restrict access to these pages for unauthorized users.
Other vulnerabilities in phpIPAM
See all- CVE-2026-67602Critical
phpIPAM before 1.8.2 contains an authentication bypass vulnerability in the REST API that allows unauthenticated attackers to gain full API access by exploiting an insecure object cache keying mechanism. The cache is keyed by lookup value alone without including the searched column, enabling an entry written during an app_id lookup to satisfy a subsequent app_code lookup, allowing attackers to use the numeric database row identifier as an API token to read, write, and delete all IP address management records.
- CVE-2026-97818High
phpIPAM through 1.8.3 has incorrect authorization for id=="admins" and id=="all" in api/controllers/User.php. This flaw allows access to functionality that should be restricted to authorized users.
- CVE-2026-75105High
phpIPAM through 1.8.1 fails to verify that a requested IP address belongs to the subnet a temporary share token was issued for. In app/temp_share/index.php and app/temp_share/address.php, when the share type is 'subnets', the subnetId parameter is used directly as a database primary key to fetch an address without confirming the address belongs to the authorized subnet. An unauthenticated party holding any valid, non-expired temporary share URL can enumerate the subnetId parameter to read every IP address record across all sections and subnets, including hostnames, DNS names, MAC addresses, owner/contact fields, and notes (which may contain credentials and configuration details).
- CVE-2026-12194Low
PHPIPAM is affected by an authenticated local file inclusion vulnerability that allows users with access to the API to execute/include arbitrary PHP files on the web server's file system. The API is not enabled by default on installations.
- CVE-2025-61078Medium
A cross-site scripting (XSS) vulnerability was found in phpIPAM v1.7.3 in the Request IP form. It allows remote attackers to inject arbitrary web script or HTML via the instructions parameter at the /app/admin/instructions/edit-result.php endpoint.
