Summary
Fix #8363. Correctly catch the error with callback when insertMany fails to initialize the document.
This can prevent DOS attack when inserting user-provided data.
This fix handles it like
Model.create([...])does.Note: I've tested
Model.bulkWrite()insertOne()/replaceOne()and I can confirm that it's not affected by this bug because$handleCallbackErrorwrap the entire bulkWrite callback handler and it catches the error duringcastBulkWrite().However, in
Model.insertMany(),parallelLimit()individual callbacks are not wrapped in that general handler (although $__insertMany is) so we need this fix.Examples
