This is due to the function identifying the support account solely by matching against publicly hardcoded constants — `user_login` `'groundhogg'` and email addresses `'support@groundhogg.io'` / `'help@groundhogg.io'` — where the `in_array()` email-equality check at line 238 is not a security boundary because any user fully controls their own email value. This makes it possible for an attacker with an account whose `user_login` is `'groundhogg'` and whose `user_email` matches one of the hardcoded support constants to have that account silently promoted to administrator — and additionally to super admin on multisite when the triggering administrator holds `manage_network_options` — resulting in full site takeover. Exploitation requires a two-actor flow: the attacker must first obtain or pre-plant an account with the hardcoded credentials (possible when open user registration is enabled or another account-creation path exists), after which a legitimate administrator must invoke the support-access feature via the `submit_ticket` or `process_send_support_access` entry points to trigger the promotion.","state":0,"publishedAt":"2026-10-10T05:31:03.178+00:00","modifiedAt":"2026-10-11T16:55:17.216+00:00","affected":[{"ecosystem":"Vendor product","name":"Groundhogg — CRM, Newsletters, and Marketing Automation","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"trainingbusinesspros\",\n                    \"product\": \"Groundhogg — CRM, Newsletters, and Marketing Automation\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.8.3\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c355658a-515a-48ed-a114-6a202e23e34b?source=cve","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.8.1/admin/help/help-page.php#L250","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.8.1/admin/help/help-page.php#L224","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.8.1/admin/help/help-page.php#L238","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.8.1/admin/help/help-page.php#L298","https://plugins.trac.wordpress.org/browser/groundhogg/tags/4.8.1/admin/help/help-page.php#L599","https://github.com/groundhoggwp/groundhogg/commit/4b413aa6e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92975","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92975","identifiers":["CVE-2026-92975"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
