CVE-2024-45336: Go Standard Library Net/http

Medium severity, CVSS 6.1. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Go Standard Library Net/http: before 1.22.11 (fixed in 1.22.11); from 1.23.0-0, before 1.23.5 (fixed in 1.23.5); from 1.24.0-0, before 1.24.0-rc.2 (fixed in 1.24.0-rc.2)
