Detailsinfo

A vulnerability was found in Eclipse BaSyx Go Components up to 1.1.2 and classified as problematic. Affected by this issue is some unknown functionality of the component Submodel Repository. The manipulation with an unknown input leads to a improper authorization vulnerability. Using CWE to declare the problem leads to CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. Impacted is confidentiality. CVE summarizes:

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.

The advisory is available at gitlab.eclipse.org. This vulnerability is handled as CVE-2026-127102 since 11/12/2026. The exploitation is known to be easy. The attack may be launched remotely. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1548.002 by the MITRE ATT&CK project.
