In versions before 3.88.0 and canary versions before 4.0.0-canary.27, an untrusted user who can query a readable collection, control its sorting, and select a protected field as the sort parameter can infer limited information about field values the user cannot read. This issue is fixed in versions 3.88.0 and 4.0.0-canary.27.
