A flaw was found in the REST Data Panache component of Quarkus. When a security constraint is applied to an entity property using the @SecureField annotation on its getter method rather than the field itself, the generated REST resource fails to enforce this constraint for filtering and sorting operations. This allows an authenticated user to infer sensitive data values by observing which records match specific filter criteria or how they are ordered, even though the values are omitted from the final response.
