CVE-2026-101322
In Eclipse BaSyx AAS Web UI versions v2-241220 through releases before v2-260924, the shared request handler attached the selected infrastructure's `Authorization` header to outgoing requests without checking the destination origin. In deployments using authentication, an attacker could induce a user to open a crafted Web UI link whose `aas` or `path` query parameter points to an attacker-controlled endpoint. The user's browser would then send the configured Basic Authentication credentials, Bearer token, or an available OAuth2 access token to that endpoint. The attacker could reuse the disclosed credential to access protected AAS services with the victim's privileges. The issue is fixed in v2-260924.
