CVE-2017-6080
To exploit the vulnerability, an attacker can send cross-domain requests directly to the REST API for users with a valid session cookie and receive the result.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
