In affected versions users who use [`HttpAuthMiddleware`](http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#module-scrapy.downloadermiddlewares.httpauth) (i.e. the `http_user` and `http_pass` spider attributes) for Splash authentication will have any non-Splash request expose your credentials to the request target. This includes `robots.txt` requests sent by Scrapy when the `ROBOTSTXT_OBEY` setting is set to `True`. Upgrade to scrapy-splash 0.8.0 and use the new `SPLASH_USER` and `SPLASH_PASS` settings instead to set your Splash authentication credentials safely. If you cannot upgrade, set your Splash request credentials on a per-request basis, [using the `splash_headers` request parameter](https://github.com/scrapy-plugins/scrapy-splash/tree/0.8.x#http-basic-auth), instead of defining them globally using the [`HttpAuthMiddleware`](http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#module-scrapy.downloadermiddlewares.httpauth).
