HighCVE-2026-57389

Groundhogg — CRM, Newsletters, and Marketing Automation <= 4.4.1 - Authenticated (Sales Representative+) Arbitrary File Deletion

Affected versions: *-4.4.1

Vulnerability type: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Affected software, patched versions and attribution

The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in all versions up to, and including, 4.4.1. This makes it possible for authenticated attackers, with Custom-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

Groundhogg <= 4.5.8 - Authenticated (Custom+) SQL Injection via 'select' Parameter

Affected versions: *-4.5.8

Vulnerability type: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Affected software, patched versions and attribution

The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to generic SQL Injection via the 'select' parameter in all versions up to, and including, 4.5.8 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 custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the attacker to hold a Groundhogg custom role with the view_contacts capability, which is granted by default to several built-in Groundhogg roles above the base subscriber level.

Groundhogg <= 4.5.5 - Authenticated (Sales Rep+) SQL Injection via 'query[select]' Parameter

Affected versions: *-4.5.5

Vulnerability type: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Affected software, patched versions and attribution

The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to generic SQL Injection via 'query[select]' 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 Sales Representative-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 sanitized Contact_Query code path can be bypassed by supplying an invalid filter type (e.g., query[filters][0][0][type]=invalid_filter_nonexistent), causing a FilterException to be caught and execution to fall through to the unsanitized Legacy_Contact_Query path.
