SQL injection vulnerability in modules/module.ab-testing.php in the Landing Pages plugin before 1.8.5 for WordPress allows remote authenticated users to execute arbitrary SQL commands via the post parameter in an edit delete-variation action to wp-admin/post.php.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
