CVE-2016-8218
Incomplete validation logic in JSON Web Token (JWT) libraries can allow unprivileged attackers to impersonate other users to the routing API, aka an "Unauthenticated JWT signing algorithm in routing" issue.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
