CVE-2018-18074
The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.93%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
