{"id":"CVE-2026-104725","state":"PUBLISHED","title":"Groundhogg <= 4.9 - Authenticated (Custom+) Privilege Escalation to 'user' Parameter","description":"The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.9 This is due to a missing ownership and capability check on the `user` parameter within the `process_edit()` function, which allows any authenticated user with the `edit_contacts` capability to reassign a contact record's linked WordPress user ID to any arbitrary account without requiring the `edit_users` or `promote_users` capabilities. This makes it possible for authenticated attackers, with sales_rep-level access and above, to escalate their privileges to administrator by linking a contact to an administrator's WordPress user ID, then creating a note containing the `{auto_login_link}` replacement tag to trigger generation of a valid auto-login permissions-key URL for the administrator-linked contact, and finally visiting that URL to authenticate as the targeted administrator. The auto-login URL is stored in the note content and is readable back by the attacker via the `view_notes` and `add_notes` capabilities that the sales_rep role holds by default.","publishedAt":"2026-10-10T05:30:59.219Z","updatedAt":"2026-10-11T16:55:17.817Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","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":"4.9","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/715b4d10-b19a-4b37-8a76-985c37975c93?source=cve","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.9/admin/contacts/contacts-page.php#L565","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.9/admin/contacts/contacts-page.php#L507","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.9/includes/classes/note.php#L58","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.9/includes/replacements.php#L1811","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.9/includes/rewrites.php#L471","https://github.com/groundhoggwp/groundhogg/commit/804abf42a","https://plugins.trac.wordpress.org/changeset?reponame=&new=3724910%40groundhogg%2Ftags%2F4.9.1&old=3724058%40groundhogg%2Ftags%2F4.9"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104725.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104725","state":"PUBLISHED","datePublished":"2026-10-10T05:30:59.219Z","dateUpdated":"2026-10-11T16:55:17.817Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-02T11:45:33.727Z"},"containers":{"cna":{"title":"Groundhogg <= 4.9 - Authenticated (Custom+) Privilege Escalation to 'user' Parameter","descriptions":[{"lang":"en","value":"The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.9 This is due to a missing ownership and capability check on the `user` parameter within the `process_edit()` function, which allows any authenticated user with the `edit_contacts` capability to reassign a contact record's linked WordPress user ID to any arbitrary account without requiring the `edit_users` or `promote_users` capabilities.
