Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.89%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
This affects all versions of package libxmljs. When invoking the libxmljs.parseXml function with a non-buffer argument the V8 code will attempt invoking the .toString method of the argument. If the argument's toString value is not a Function object V8 will crash.
