| Summary | Scrapy cookie-setting is not restricted based on the public suffix list ### Impact Responses from domain names whose public domain name suffix contains 1 or more periods (e.g. responses from `example.co.uk`, given its public domain name suffix is `co.uk`) are able to set cookies that are included in requests to any other domain sharing the same domain name suffix. ### Patches Upgrade to Scrapy 2.6.0, which restricts cookies with their domain set to any of those in the [public suffix list](https://publicsuffix.org/). If you are using Scrapy 1.8 or a lower version, and upgrading to Scrapy 2.6.0 is not an option, you may upgrade to Scrapy 1.8.2 instead. ### Workarounds The only workaround for unpatched versions of Scrapy is to [disable cookies altogether](https://docs.scrapy.org/en/latest/topics/downloader-middleware.html#std-setting-COOKIES_ENABLED), or [limit target domains](https://docs.scrapy.org/en/latest/topics/spiders.html#scrapy.spiders.Spider.allowed_domains) to a subset that does not include domain names with one of the public domain suffixes affected (those with 1 or more periods). ### References * https://publicsuffix.org/ ### For more information If you have any questions or comments about this advisory: * [Open an issue](https://github.com/scrapy/scrapy/issues) * [Email us](mailto:opensource@zyte.com) |
