Low risk20th percentile — higher than 20% of all known CVEs
Summary
The Groundhogg plugin for WordPress (versions up to and including 4.5.4) is vulnerable to generic SQL injection via the 'after' parameter. Authenticated attackers with Sales Manager-level access or above can append additional SQL queries to existing ones, enabling extraction of sensitive data from the database. Additionally, the AJAX handler wp_ajax_groundhogg_get_contacts_table has its capability check commented out and performs no nonce verification, allowing any authenticated user to reach the vulnerable code path.
Risk Assessment
The risk involves potential theft of confidential data from the WordPress database, such as customer data, passwords, or API keys, by an attacker with relatively low privileges.
Recommendation
Immediately update the Groundhogg plugin to version 4.5.5 or later. If an update is not possible, temporarily disable the plugin or restrict access to Sales Manager roles.
Original NVD description (English source)
The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to generic SQL Injection via the 'after' parameter in all versions up to, and including, 4.5.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Sales Manager-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The AJAX handler wp_ajax_groundhogg_get_contacts_table has its capability check commented out and performs no nonce verification, meaning any authenticated user regardless of role can reach the vulnerable code path.
