CVE-2020-26527
Cross-origin resource sharing trusts random origins by accepting the arbitrary 'Origin: example.com' header and responding with 200 OK and a wildcard 'Access-Control-Allow-Origin: *' header.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.91%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
