Vulnerability Report: GO-2025-3420
standard library- CVE-2024-45336
- Affects: net/http
- Published: Jan 28, 2025
- Modified: Jan 30, 2025
The HTTP client drops sensitive headers after following a cross-domain redirect. For example, a request to a.com/ containing an Authorization header which is redirected to b.com/ will not send that header to b.com. In the event that the client received a subsequent same-domain redirect, however, the sensitive headers would be restored. For example, a chain of redirects from a.com/, to b.com/1, and finally to b.com/2 would incorrectly send the Authorization header to b.com/2.
