CVE-2016-8615
If cookie state is written into a cookie jar file that is later read back and used for subsequent requests, a malicious HTTP server can inject new cookies for arbitrary domains into said cookie jar.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.72%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
