The ruleid _XSS_script_tag__Parameter__AllQueryArguments_Body suggests a XSS script tag detected (> or < signs), could you check your request payload and confirm that?

    Hi Amine_Kadimi ,

    Thanks for reply.

    Yes the body of the request has "<>" because it's an xml.

    What's the best way to exclude it and do you have any documentation on what exactly is checked by your rules?

    Thanks!
