The Popup Builder plugin 2.2.8 through 2.6.7.6 for WordPress is vulnerable to SQL injection (in the sgImportPopups function in sg_popup_ajax.php) via PHP Deserialization on attacker-controlled data with the attachmentUrl POST variable. This allows creation of an arbitrary WordPress Administrator account, leading to possible Remote Code Execution because Administrators can run PHP code on Wordpress instances. (This issue has been fixed in the 3.x branch of popup-builder.)
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.
