to version 1.8.3, 2.6.2 or higher.
Scrapy is a high-level web crawling and web scraping framework, used to crawl websites and extract structured data from their pages.
Affected versions of this package are vulnerable to Credential Exposure via the process_request()
function in downloadermiddlewares/httpproxy.py
. A proxy can leak credentials to another proxy if third-party downloader middlewares leave Proxy-Authentication
headers unchanged when updating proxy
metadata for a new request.
NOTE: To fully mitigate the effects of vulnerability, replacing or upgrading the third-party downloader middleware might be necessary after upgrading.
