In Eclipse BaSyx Go Components versions up to and including 1.1.2, ABAC-enabled deployments of the Submodel Repository and the AAS Environment return Submodel Elements that the caller is not authorized to read from `GET /submodels/{submodelIdentifier}/submodel-elements`.
If an access rule grants READ on a single Submodel Element through a `$sme` `REFERABLE` object, the list route returns every element of that Submodel, including its value, as soon as one element matches the caller's rules. The single-element route and the full Submodel read enforce the same rule and deny access to the other elements. An authenticated caller with a READ grant for one element of a Submodel can therefore read all other elements of that Submodel.
The issue is fixed in Eclipse BaSyx Go Components v1.1.3.
