Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In Eclipse BaSyx Go Components versions up to and including 1.0.0, ABAC-enabled deployments are vulnerable to an authorization bypass caused by inconsistent trailing-slash handling between the ABAC middleware and the HTTP router. The shared router configuration used Chi's `middleware.StripSlashes`, so a request such as `GET /shells/` was dispatched to the registered `GET /shells` route. However, the ABAC middleware evaluated the original request path including the trailing slash. If ABAC route lookup did not find a matching slash-suffixed route, the request was passed onward and the router then stripped the slash and executed the protected handler without the intended ABAC authorization decision and without the expected ABAC query filters. An unauthenticated or unauthorized network attacker could append a trailing slash to protected API routes to reach handlers that should have been denied by ABAC policy. Depending on the exposed component, HTTP method, and deployed policy, this could allow unauthorized read, create, update, delete, or upload operations. The issue affects ABAC-enabled deployments of services that use the shared router and ABAC middleware, including AAS Repository, Submodel Repository, AAS Registry, Submodel Registry, Concept Description Repository, Discovery, AAS Environment upload, and related services. The issue is fixed in Eclipse BaSyx Go Components v1.0.1.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-07.

Recommended fix High confidence

Eclipse BaSyx Go Components v1.0.1

  1. 1. Identify all deployed instances of Eclipse BaSyx Go Components v1.0.0 or earlier that have ABAC enabled.
  2. 2. Obtain Eclipse BaSyx Go Components v1.0.1 from the official Eclipse BaSyx repository or release distribution channel.
  3. 3. Backup all configuration files, policies, and any persisted data for the affected components.
  4. 4. Stop all running services that use the affected components (AAS Repository, Submodel Repository, AAS Registry, Submodel Registry, Concept Description Repository, Discovery, AAS Environment upload, and related services).
  5. 5. Replace the existing Eclipse BaSyx Go Components binaries/libraries with v1.0.1.
  6. 6. Restore the backed-up configuration files and ABAC policy configurations.
  7. 7. Start the services and verify they are running correctly.
  8. 8. Test that ABAC authorization is correctly enforced by attempting requests with trailing slashes (e.g., GET /shells/) on protected routes - these should now be properly denied according to ABAC policy.
