CVE-2026-128790

Vulnerability record

High 7.1

Description

In Eclipse BaSyx Go Components versions up to and including 1.1.2, ABAC-enabled deployments of the Submodel Repository and the AAS Environment do not apply an access rule's `FILTERLIST` fragment filters to single Submodel reads. `GET /submodels` removes the fields that a rule's `FILTERLIST` hides, but `GET /submodels/{submodelIdentifier}` and `GET /submodels/{submodelIdentifier}/$metadata` return them unfiltered. An authenticated caller with READ access to a Submodel can therefore read fields that the access rules hide from them, for example `supplementalSemanticIds` keys that name the other parties allowed to read the Submodel. If versioning is enabled (`history.mode` set to `api` or `audit`), `GET /submodels/{submodelIdentifier}/$history` and `GET /shells/{aasIdentifier}/$history` in the Submodel Repository, AAS Repository and AAS Environment return the complete stored version without applying the rule's formula or fragment filters. A caller whose rules grant READ on these routes can read fields that the access rules hide, and Submodels and Asset Administration Shells that the direct read does not return to them at all. The issue is fixed in Eclipse BaSyx Go Components v1.1.3.
