CVE-2020-12283
Sourcegraph before 3.15.1 has a vulnerable authentication workflow because of improper validation in the SafeRedirectURL method in cmd/frontend/auth/redirect.go, such as for the //foo//example.com substring.
Does this matter?
Lower severity and a low EPSS score (1.33%). Track it; it rarely justifies an emergency change on its own.
