Blankie not sanitizing request payload

[Kumaraditya03]

We have registered the plugin following the documentation.
We have our request payload with <script> in it...but blankie is not sanitizing it.
Payload:
fieldName: "<script>alert("hi")</script>"
expected behaviour on sanitization;
fieldName:""
current behaviour:
fieldName: "<script>alert("hi")</script>"

Is this the usual behaviour of blankie or does it sanitize the request payload with inline scripts?
Team, please let me know about the above.
