CVE-2017-6145
This service does not properly re-validate cookies when making that conversion, allowing once-valid but now expired cookies to be converted to valid tokens.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
