wordpress - Is this dangerous to my Rails App? -

we hosted on heroku, , have newrelic add on. every day check errors, , every day error comes up.

action , type

middleware/rack/rack::methodoverride#call eoferror 

message

bad content body     

this rails application, , figure it's not doing in particular other returning 440 response status because there nothing @ url trying access.

url

/wp-admin/admin-ajax.php 

through google-fu found article pertaining being brute force attack on wordpress sites.

my specific question is:

do worry this?

inherited site , not sure if happens, , if rails applications don't have worry about? seems targeted towards wordpress, can't find documentation on whether should doing more stop this.

other pinged urls don't exist on application

/sites/all/libraries/elfinder/php/connector.minimal.php  /license.php  /tiny_mce/plugins/tinybrowser/upload_file.php  

any enlightenment on subject great. stack trace available if needed. in advance, overflowers.

as long don't have route configured handle requests have worry getting spammed these requests , losing network resources. they'll recieve 404 not found error when try reach , there nothing can except slow site if spam requests. if can ban ip address.
