Description

In Eclipse BaSyx Go Components versions up to and including 1.1.3, ABAC-enabled deployments match `ROUTE` access rules against the fully decoded request path, while the router routes on the raw, still encoded path. An encoded slash (`%2F`) inside a path value is a segment separator for the access check but part of the value for the router, so a request can match a narrow `ROUTE` rule while the handler returns a different, larger resource.

An authenticated caller whose rules grant READ only on parts of a resource can therefore read the whole resource. In the DPP API, a rule such as `/v1/dpps/*/elements/*`, meant to grant only passport elements, also grants the complete passport whose identifier contains `/elements/`. In the Submodel Repository, AAS Repository and AAS Environment, a rule such as `/submodels/*/submodel-elements/*/attachment`, meant to grant only file attachments, also grants the complete element whose stored idShort contains `%2F`.

The issue is fixed in Eclipse BaSyx Go Components v1.1.4.
