Affected packages
• PyPI scrapy-splash: < 0.8.0 → fixed in 0.8.0
Description
Impact
If you use `HttpAuthMiddleware` (i.e. the `http_user` and `http_pass` spider attributes) for Splash authentication, any non-Splash request will expose your credentials to the request target. This includes `robots.txt` requests sent by Scrapy when the `ROBOTSTXT_OBEY` setting is set to `True`.
Patches
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.
Workarounds
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.
