The endpoint's permission callback checks only the role-level view_contacts capability and read_single() returns the full contact record by sequential integer ID without the object-level view_contact ownership check applied elsewhere in the codebase. This makes it possible for authenticated attackers holding view_contacts but not view_others_contacts — notably Groundhogg's built-in Sales Rep role, designed to see only its own contacts — to read any contact record on the site, including PII, contact meta, owner IDs, the admin edit URL, and (for contacts linked to a WordPress user) that user's full capability set.","publishedAt":"2026-08-05T06:37:56.758Z","updatedAt":"2026-08-05T13:30:11.571Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["trainingbusinesspros Groundhogg — CRM, Newsletters, and Marketing Automation"],"affected":[{"vendor":"trainingbusinesspros","product":"Groundhogg — CRM, Newsletters, and Marketing Automation","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.5.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7fe3d251-4edf-4d94-a946-0aa918135784?source=cve","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.5.2/api/v4/contacts-api.php#L426","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.5.2/api/v4/contacts-api.php#L946","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.5.2/api/v4/base-object-api.php#L124","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.5.2/includes/main-roles.php#L163","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.5.2/includes/main-roles.php#L374","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.5.2/includes/main-roles.php#L43","https://plugins.trac.wordpress.org/changeset?new=3569222%40groundhogg%2Ftags%2F4.5.3&old=3562726%40groundhogg%2Ftags%2F4.5.2","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.5.3/api/v4/contacts-api.php#L437"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/11xxx/CVE-2026-11454.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-11454","state":"PUBLISHED","datePublished":"2026-08-05T06:37:56.758Z","dateUpdated":"2026-08-05T13:30:11.571Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-06T12:45:02.962Z"},"containers":{"cna":{"title":"Groundhogg — CRM, Newsletters, and Marketing Automation <= 4.5.2 - Insecure Direct Object Reference","descriptions":[{"lang":"en","value":"The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.5.2 via the GET /wp-json/gh/v4/contacts/<id> REST endpoint.
