When a Request object with cookies defined gets a redirect response causing a new Request object to be scheduled, the cookies defined in the original Request object are no longer copied into the new Request object.
If you manually set the Cookie header on a Request object and the domain name of the redirect URL is not an exact match for the domain of the URL of the original Request object, your Cookie header is now dropped from the new Request object.
The old behavior could be exploited by an attacker to gain access to your cookies. Please, see the cjvr-mfj7-j4j8 security advisory for more
information.
Note: It is still possible to enable the sharing of cookies between different domains with a shared domain suffix (e.g. example.com and any subdomain) by defining the shared domain suffix (e.g. example.com) as the cookie domain when defining your cookies. See the documentation of the Request class for more information.
When the domain of a cookie, either received in the Set-Cookie header of a response or defined in a Request object, is set to a public suffix <https://publicsuffix.org/>_, the cookie is now ignored unless the cookie domain is the same as the request domain.
The old behavior could be exploited by an attacker to inject cookies from a controlled domain into your cookiejar that could be sent to other domains not controlled by the attacker. Please, see the mfjm-vh54-3f96 security advisory for more information.
1.8.1
Security bug fix:
If you use HttpAuthMiddleware (i.e. the http_user and http_pass spider attributes) for HTTP authentication, any request exposes your credentials to the request target.
To prevent unintended exposure of authentication credentials to unintended domains, you must now additionally set a new, additional spider attribute, http_auth_domain, and point it to the specific domain to which the authentication credentials must be sent.
If the http_auth_domain spider attribute is not set, the domain of the first request will be considered the HTTP authentication target, and authentication credentials will only be sent in requests targeting that domain.
If you need to send the same HTTP authentication credentials to multiple domains, you can use w3lib.http.basic_auth_header instead to set the value of the Authorization header of your requests.
If you really want your spider to send the same HTTP authentication credentials to any domain, set the http_auth_domain spider attribute to None.
Finally, if you are a user of scrapy-splash, know that this version of Scrapy breaks compatibility with scrapy-splash 0.7.2 and earlier. You will need to upgrade scrapy-splash to a greater version for it to continue to work.
When a :class:~scrapy.http.Request object with cookies defined gets a
redirect response causing a new :class:~scrapy.http.Request object to be
scheduled, the cookies defined in the original
:class:~scrapy.http.Request object are no longer copied into the new
:class:~scrapy.http.Request object.
If you manually set the Cookie header on a
:class:~scrapy.http.Request object and the domain name of the redirect
URL is not an exact match for the domain of the URL of the original
:class:~scrapy.http.Request object, your Cookie header is now dropped
from the new :class:~scrapy.http.Request object.
The old behavior could be exploited by an attacker to gain access to your
cookies. Please, see the cjvr-mfj7-j4j8 security advisory_ for more
information.
.. note:: It is still possible to enable the sharing of cookies between
different domains with a shared domain suffix (e.g.
example.com and any subdomain) by defining the shared domain
suffix (e.g. example.com) as the cookie domain when defining
your cookies. See the documentation of the
:class:~scrapy.http.Request class for more information.
When the domain of a cookie, either received in the Set-Cookie header
of a response or defined in a :class:~scrapy.http.Request object, is set
to a public suffix <https://publicsuffix.org/>_, the cookie is now
ignored unless the cookie domain is the same as the request domain.
The old behavior could be exploited by an attacker to inject cookies into
your requests to some other domains. Please, see the mfjm-vh54-3f96 security advisory_ for more information.
