CVE-2023-45143

Summary

CVE-2023-45143 affects Undici, an HTTP/1.1 client for Node.js, prior to version 5.26.2. The vulnerability arises from Undici's handling of cookies during cross-origin redirects. While it clears Authorization headers, it fails to clear Cookie headers, which are forbidden in browser environments. Undici's deviation from the specification can lead to unintended cookie leaks to third-party sites or attackers controlling the redirection target, potentially exposing sensitive information. This issue was resolved in version 5.26.2, and there are no known workarounds for affected versions.
