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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
