Severity: 3-Major


In cases where the protected input field is not located under the form tag, the Remove Event Listener removes the malicious event listeners of the input field, but the field itself is missing in the traffic (that is being sent on submit).


In an edge-case situation, the entered values are not sent when submitting the form.


Protected inputs located outside of the form tag. For example: <form> ... </form> <input name="username">



Fix Information

Remove Event Listener feature now supports cases where an input field is not inside the form.
