CVE-2022-32148: Golang Go

Medium severity, CVSS 6.5. EPSS: 1.4% chance of exploitation in the next 30 days.

Improper exposure of client IP addresses in net/http before Go 1.17.12 and Go 1.18.4 can be triggered by calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the X-Forwarded-For header, which causes ReverseProxy to set the client IP as the value of the X-Forwarded-For header.

Affected products

• Golang Go: before 1.17.12 (fixed in 1.17.12); from 1.18.0, before 1.18.4 (fixed in 1.18.4)
