Add the missing Go module mapping, affected/patched version information, summary, CVSS 4.0 vector, and source code location for CVE-2026-15704 / GHSA-86p5-cmgc-c94w.
The affected Go module is github.com/eclipse-basyx/basyx-go-components, as declared by the root go.mod at both the vulnerable v1.0.0 tag and the fixed v1.0.1 tag.
In v1.0.0, internal/common/router_error_handlers.go configures API routers with Chi's middleware.StripSlashes. In ABAC-enabled deployments, authorization evaluates the original request path while the router can subsequently strip the trailing slash and dispatch the corresponding protected non-slash route. An unauthorized request such as /shells/ can therefore miss the intended ABAC route decision and still reach the /shells handler.
The upstream fix eclipse-basyx/basyx-go-components#442 removes StripSlashes from ConfigureAPIRouter. Its regression tests explicitly change trailing-slash requests from successful or method-matched routing to HTTP 404 and verify that the protected collection handler is not called. Additional integration cases cover trailing-slash requests across repository, registry, discovery, upload, and related service routes.
