DataEase versions up to and including 2.10.3 contain an authentication bypass in `io.dataease.auth.filter.TokenFilter`. The filter passes the raw, unnormalized request URI to `WhitelistUtils.match()`, which only checks for whitelisted prefixes such as `/geo/`, `/customGeo/`, `/map/`, `/oauth2/`, and `/websocket` without resolving `..` segments. By prepending a whitelisted prefix and traversing back into the configured `server.servlet.context-path`, an attacker bypasses the filter while Tomcat still routes the request to the genuine, protected controller. This collapses the entire `/de2api` surface (user management, datasources, dashboards, exports) into unauthenticated access.
