CVE-2024-1968Public exploitNetwork attack vector

Credential disclosure via retained cross-origin Authorization header

Published May 20, 2024 · Updated Aug 1, 2024

Information disclosure in Scrapy before 2.11.2 allows man-in-the-middle attackers to read Authorization headers during redirects. The _build_redirect_request function compared only network locations, so a same-host HTTPS-to-HTTP redirect retained the Authorization header. Exploitation requires an authenticated crawl to follow an attacker-influenced downgrade redirect while plaintext traffic is observable.
