CVE-2023-45289

A maliciously crafted HTTP redirect could cause sensitive headers to be unexpectedly forwarded.

MEDIUM 4.3EPSS 1.08%

Does this matter?

Lower severity and a low EPSS score (1.08%). Track it; it rarely justifies an emergency change on its own.

Description

When following an HTTP redirect to a domain which is not a subdomain match or exact match of the initial domain, an http.Client does not forward sensitive headers such as "Authorization" or "Cookie". For example, a redirect from foo.com to www.foo.com will forward the Authorization header, but a redirect to bar.com will not. A maliciously crafted HTTP redirect could cause sensitive headers to be unexpectedly forwarded.
