Low risk20th percentile — higher than 20% of all known CVEs
Summary
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.
Risk Assessment
An authenticated attacker with marketer-level access or higher can append additional SQL queries to existing ones, allowing extraction of sensitive information from the database, such as user data or passwords.
Recommendation
Immediately update the Groundhogg plugin to version 4.5.6 or later, which includes a fix for the SQL injection vulnerability.

The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to generic SQL Injection via the 'search' parameter in all versions up to, and including, 4.5.5 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 marketer-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
