{"id":"PYSEC-2021-364","details":"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).","aliases":["CVE-2021-41124","GHSA-823f-cwm9-4g74"],"modified":"2023-11-08T04:06:51.977544Z","published":"2021-10-05T21:15:00Z","references":[{"type":"FIX","url":"https://github.com/scrapy-plugins/scrapy-splash/commit/2b253e57fe64ec575079c8cdc99fe2013502ea31"},{"type":"ADVISORY","url":"https://github.com/scrapy-plugins/scrapy-splash/security/advisories/GHSA-823f-cwm9-4g74"}],"affected":[{"package":{"name":"scrapy-splash","ecosystem":"PyPI","purl":"pkg:pypi/scrapy-splash"},"ranges":[{"type":"GIT","repo":"https://github.com/scrapy-plugins/scrapy-splash","events":[{"introduced":"0"},{"fixed":"2b253e57fe64ec575079c8cdc99fe2013502ea31"}]},{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.8.0"}]}],"versions":["0.2","0.3","0.4","0.5","0.6","0.6.1","0.7","0.7.1","0.7.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/scrapy-splash/PYSEC-2021-364.yaml"}}],"schema_version":"1.7.3"}
