Groundhogg vulnerabilities

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.

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.

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.

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.

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.

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.

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.

Versions of Groundhogg below 4.4.1 have a broken access control issue for subscribers, potentially allowing unauthorized access to data.

In Groundhogg versions <= 4.4, there is a vulnerability that allows sales representatives to delete arbitrary files.
