CVE-2017-16226
In affected versions, untrusted user input is able to access the global function constructor, effectively allowing arbitrary code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.54%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
