CVE-2026-104725 Details
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.
A privilege escalation vulnerability has been identified in the Groundhogg CRM, Newsletters, and Marketing Automation plugin for WordPress, affecting all versions through 4.9. The issue arises from a lack of proper ownership and capability checks on the 'user' parameter in the 'process_edit()' function. This flaw enables any authenticated user with the 'edit_contacts' capability to arbitrarily reassign a contact's linked WordPress user ID to any account, bypassing the need for 'edit_users' or 'promote_users' capabilities. As a result, authenticated attackers with sales_rep-level access can escalate their privileges to administrator by linking a contact to an administrator's WordPress user ID. They can then create a note with the '{auto_login_link}' tag, generating a valid auto-login URL for the administrator-linked contact, which, when visited, authenticates them as the targeted administrator.
Users are advised to update the Groundhogg plugin to version 4.9.1 or later, where this vulnerability has been patched.
