Scrapy 2.6.2 (2022-07-25)
Security bug fix:
When :class:
~scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware
processes a request with :reqmeta:proxy
metadata, and that :reqmeta:proxy
metadata includes proxy credentials, :class:~scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware
sets theProxy-Authentication
header, but only if that header is not already set.There are third-party proxy-rotation downloader middlewares that set different :reqmeta:
proxy
metadata every time they process a request.Because of request retries and redirects, the same request can be processed by downloader middlewares more than once, including both :class:
~scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware
and any third-party proxy-rotation downloader middleware.These third-party proxy-rotation downloader middlewares could change the :reqmeta:
proxy
metadata of a request to a new value, but fail to remove theProxy-Authentication
header from the previous value of the :reqmeta:proxy
metadata, causing the credentials of one proxy to be sent to a different proxy.To prevent the unintended leaking of proxy credentials, the behavior of :class:
~scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware
is now as follows when processing a request:
If the request being processed defines :reqmeta:
proxy
metadata that includes credentials, theProxy-Authorization
header is always updated to feature those credentials.If the request being processed defines :reqmeta:
proxy
metadata without credentials, theProxy-Authorization
header is removed unless it was originally defined for the same proxy URL.To remove proxy credentials while keeping the same proxy URL, remove the
Proxy-Authorization
header.If the request has no :reqmeta:
proxy
metadata, or that metadata is a falsy value (e.g.None
), theProxy-Authorization
header is removed.It is no longer possible to set a proxy URL through the :reqmeta:
proxy
metadata but set the credentials through theProxy-Authorization
header. Set proxy credentials through the :reqmeta:proxy
metadata instead.
