  "details": "Versions of `loopback-connector-mongodb` before 3.6.0 are vulnerable to NoSQL injection.\n\nMongoDB Connector for LoopBack fails to properly sanitize a filter passed to query the database by allowing the dangerous `$where` property to be passed to the MongoDB Driver. The Driver allows the special `$where` property in a filter to execute JavaScript (client can pass in a malicious script) on the database Driver. This is an [intended feature of MongoDB](https://docs.mongodb.com/manual/core/server-side-javascript/) unless disabled ([instructions here](https://docs.mongodb.com/manual/core/server-side-javascript/#disable-server-side-js)).\n\nA proof of concept malicious query:\n\n```\nGET /POST filter={\"where\": {\"$where\": \"function(){sleep(5000); return this.title.contains(\u0027Hello\u0027);}\"}}\n```\n\nThe above makes the database sleep for 5 seconds and then returns all \u201cPosts\u201d with the title containing the word `Hello`.\n\n\n\n\n## Recommendation\n\nUpdate to version 3.6.0 or later.",
