MongoDB's JSON Schema validation contains a vulnerability that allows authenticated users with readWrite privileges to crash the mongod server by submitting a BSON document with a malformed numeric field name in an array. This flaw arises from improper handling of exceptions during error generation, leading to an uncaught exception that terminates the server process. Organizations using MongoDB should prioritize addressing this issue to prevent potential service disruptions.

Original NVD Description

A flaw in MongoDB's JSON Schema validation error generation code allows an authenticated user with readWrite privileges to crash the mongod server. When a BSON document containing an array with a malformed numeric field name fails a $jsonSchema items type constraint, the error generation path performs unsafe numeric conversion on the user-controlled field name without proper exception handling, resulting in an uncaught exception that terminates the server process. This is possible because incoming wire protocol BSON validation does not enforce that array element field names are valid, in-range numeric indices.
