CVE-2021-41124

Description

Scrapy-splash is a library which provides Scrapy and JavaScript integration. 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). Alternatively, make sure all your requests go through Splash. That includes disabling the [robots.txt middleware](https://docs.scrapy.org/en/latest/topics/downloader-middleware.html#topics-dlmw-robots).
