Description
Scrapy-splash is a library which provides Scrapy and JavaScript integration. In affected versions users who use `HttpAuthMiddleware` (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, instead of defining them globally using the `HttpAuthMiddleware`. Alternatively, make sure all your requests go through Splash. That includes disabling the robots.txt middleware.
Affected configurations
