The package jointjs before 3.3.0 are vulnerable to Prototype Pollution via util.setByPath (https://resources.jointjs.com/docs/jointjs/v3.2/joint.htmlutil.setByPath).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
