Detailsinfo

A vulnerability classified as problematic has been found in Eclipse BaSyx Go Components up to 1.1.2. This affects an unknown code of the component Submodel Repository. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality. The summary by CVE is:

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.

The advisory is shared at gitlab.eclipse.org. This vulnerability is uniquely identified as CVE-2026-128790 since 11/13/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1068 for this issue.

Upgrading to version 1.1.3 eliminates this vulnerability.
