Groundhogg vulnerabilities
18 known CVE vulnerabilities in Groundhogg, translated and rated.
- CVE-2026-92975High
The Groundhogg plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 4.8.3. The create_support_user() function identifies the support account solely by matching against publicly hardcoded constants, allowing an attacker with an account having login 'groundhogg' and matching email to be promoted to administrator, and to super admin on multisite.
- CVE-2026-104725High
The Groundhogg plugin for WordPress up to version 4.9 is vulnerable to privilege escalation. Missing ownership and capability checks in the 'process_edit()' function allow authenticated users with 'edit_contacts' capability (e.g., sales reps) to reassign a contact to any WordPress account, including an administrator, and then use the auto-login URL to authenticate as that administrator.
- CVE-2026-104385High
Groundhogg plugin in versions up to and including 4.8.3 contains a Sensitive Data Exposure vulnerability exploitable by an unauthenticated attacker.
- CVE-2026-104408High
The Groundhogg plugin for WordPress (versions up to 4.8.3) contains a Blind SQL Injection vulnerability due to improper neutralization of special elements in SQL commands.
- CVE-2026-97644High
The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to privilege escalation via contact identity rebinding. The create_contact function in the v3 REST endpoint is gated only by the add_contacts capability and forwards the full payload, including user_id, to the upsert path, bypassing ownership guards. This allows attackers with Sales Representative-level access and above to rebind a contact to an Administrator's user ID and then use the v4 email-test endpoint to gain an admin session.
- CVE-2026-85310Medium
import_contacts Path Traversal in Groundhogg <= 4.7.1 versions.
- CVE-2026-81741Medium
The Groundhogg — CRM, Newsletters, and Marketing Automation WordPress plugin before version 4.7.2 does not restrict the redirect target of its email preference confirmation flow to the site's own host, allowing unauthenticated attackers to redirect visitors to an arbitrary external URL by way of a crafted link.
- CVE-2026-81660High
The Groundhogg — CRM, Newsletters, and Marketing Automation WordPress plugin before 4.5.13 does not validate or escape values submitted to some optional web form fields before storing and outputting them in an administrative area, allowing unauthenticated users to perform Stored Cross-Site Scripting attacks against high privilege users.
- CVE-2026-18387Medium
The Groundhogg plugin for WordPress up to version 4.5.14 is vulnerable to SQL injection via the tag_query parameter. Insufficient escaping and lack of query preparation allow authenticated attackers with vendor-level access to append additional SQL queries, potentially extracting sensitive information. Exploitation requires triggering the Legacy_Contact_Query code path via an unknown filter type.
- CVE-2026-11454Medium
The Groundhogg plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 4.5.2. The REST endpoint GET /wp-json/gh/v4/contacts/<id> only checks the view_contacts capability, not view_others_contacts, allowing authenticated attackers (e.g., Sales Rep role) to read any contact record, including PII, contact meta, owner IDs, admin edit URLs, and full capability sets of linked WordPress users.
- CVE-2026-57389High
The Groundhogg WordPress plugin up to version 4.4.1 contains a Path Traversal vulnerability that allows unauthorized access to files outside the restricted directory.
- CVE-2026-14029Medium
The Groundhogg plugin for WordPress (versions up to 4.5.8) is vulnerable to SQL injection via the 'select' parameter. An authenticated attacker with custom-level access or higher can append additional SQL queries, enabling extraction of sensitive database information.
- CVE-2026-13333Medium
The Groundhogg plugin for WordPress (versions up to 4.5.5) is vulnerable to generic SQL injection via the 'query[select]' parameter. Insufficient escaping and lack of prepared statements allow authenticated attackers with Sales Representative-level access or higher to append additional SQL queries, potentially extracting sensitive database information.
- CVE-2026-13331Medium
The Groundhogg plugin for WordPress (CRM, newsletters, and marketing automation) in versions up to and including 4.5.5 is vulnerable to generic SQL injection via the 'search' parameter. This is due to insufficient escaping of user-supplied input and lack of proper preparation of SQL queries.
- CVE-2026-57667High
The Groundhogg plugin for WordPress versions 4.5 and earlier contains an SQL injection vulnerability in the Sales Representative module. An attacker can exploit this flaw to execute unauthorized database queries.
- CVE-2026-40793Medium
Versions of Groundhogg below 4.4.1 have a broken access control issue for subscribers, potentially allowing unauthorized access to data.
- CVE-2026-40727High

- CVE-2025-12750Medium
The Groundhogg plugin for WordPress is vulnerable to SQL injection via the 'term' parameter in all versions up to and including 4.2.6.1 due to insufficient escaping and lack of preparation on the SQL query. This allows authenticated attackers with Administrator-level access and above to append additional SQL queries to extract sensitive information from the database.
