The Popup Builder WordPress plugin before 4.1.1 does not sanitise and escape the sgpb-subscription-popup-id parameter before using it in a SQL statement in the All Subscribers admin dashboard, leading to a SQL injection, which could also be used to perform Reflected Cross-Site Scripting attack against a logged in admin opening a malicious link
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.
