CVE-2022-0235Public exploitNetwork attack vector

Credential disclosure via cross-domain redirect header forwarding

Published Jan 16, 2022 · Updated Aug 2, 2024

Information disclosure in node-fetch before 2.6.7 and 3.0.0 through 3.1.0 allows remote attackers to obtain request credentials. During cross-domain redirects, the fetch redirect handler reuses the original request headers instead of removing authorization, WWW-Authenticate, cookie, and cookie2 values. Exploitation requires an application to fetch an attacker-influenced URL with sensitive headers and follow a redirect to a domain controlled by the attacker.
