Workaround
As a temporary workaround, developers can manually sanitize user input before passing it to the setFields method. This involves escaping special characters and ensuring that the input is properly formatted for SQL queries. Here's an example of how to sanitize user input in JavaScript:
const sanitizedInput = userInput.replace(/'/g, "''");
squel.insert().into('buh').setFields({ foo: sanitizedInput }).toString();
