🚀 Feature Proposal

We all know about select:false & sanitizeProjection what it does. For certain query operations like find(), findById(), or findOne(), I, as a developer, want to ensure that no sensitive data is queried. I intend to disable the inclusion of such fields explicitly, even when attempting to retrieve them using syntax like find({}, '+password') or through population like .populate({ path: 'users', select: '+password' }). If I provide sanitizeProjection as an optional parameter, it should handle this exclusion for me.

Here we handle the projection and population from query parameter.

Or any other suggestions?

Example:

const userSchema = new Schema({
  name: { type: String, required: true },
  password: { type: String, required: true, select: false }
})

const result = await User.find({}, '+password', {
  sanitizeProjection: true
})

// At this point it return "name" and "password" both
// Requested features will return only "name"

Motivation

Motivation

The motivation stems from the ongoing development of the mongoose-query-maker package, where precise control over query parameters is fundamental for filtering, pagination, selection, and population in a controlled way with proper security via query parameter. Currently we're developing v3 for this, which can make it very easier from v2.

sanitizeProjection is more to protect against cases like UserModel.findById(_id).select({ name: '$password' });, which would replace the name field with the contents of the password field. That's currently the only purpose for sanitizeProjection.

However, you do make a good point that sanitizeProjection should protect against sensitive data ending up in the result. We will consider adding this for our next release and see if this breaks any existing tests.
