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).","published":"2026-08-17T21:16:49.473","modified":"2026-08-17T21:16:49.473","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/phpipam/phpipam/commit/2980be03652c0eb1db9fe2bcefaa210c854b9aea","label":"phpipam/phpipam@2980be0"},"references":[{"type":"WEB","url":"https://github.com/phpipam/phpipam"},{"type":"WEB","url":"https://github.com/phpipam/phpipam/commit/2980be03652c0eb1db9fe2bcefaa210c854b9aea"},{"type":"WEB","url":"https://github.com/phpipam/phpipam/issues/4623"},{"type":"WEB","url":"https://github.com/phpipam/phpipam/releases/tag/v1.8.2"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/phpipam-temporary-subnet-share-information-disclosure-via-address-parameter"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T21:16:49.473"}}
