Re-check the WeKnora advisory's affected range and any later security releases before deployment. The vendor advisory, published on 6 March 2026, identifies CVE-2026-30856 and lists versions through `0.2.14` as affected, with `0.3.0` patched. A naming collision in the client's tool registry could replace the intended implementation with a malicious server's tool; injected tool output could then influence further actions. [WeKnora advisory](https://github.com/Tencent/WeKnora/security/advisories/GHSA-67q9-58vj-32qx).\n\nThis is a dispatch-integrity problem as well as a prompt-injection problem. A familiar displayed name does not establish which remote server receives a call. CWE-706 describes names that resolve to resources outside their intended control boundary.
