Detailed vulnerability description
The vulnerability allows a remote attacker to bypass implemented authorization.
The vulnerability exists due to incorrect authorization checks. A remote authenticated attacker can "guess and check" the value of a model field they do not have access to assume they can read at least one other field in the model, then construct filter expressions for an inaccessible field to filter a collection and reconstruct the value of the inaccessible field.
