I think we have to add a new check and use pc.getCurrentThreadScope() to search the undefined scope inside the thread.
https://trycf.com/gist/70a93d54de43ba4df2202c6abc2f58bb/lucee5?theme=monokai

// search in the thread scope if (pc.hasFamily() && ((PageContextImpl) pc).getCurrentThreadScope() != null) { rtn = ((PageContextImpl) pc).getCurrentThreadScope().get(key, _null); if (rtn != _null) { if (debug && !((PageContextImpl) pc).isThreads(rtn)) debugCascadedAccess(pc, "thread", key); return rtn; } }

Inside the thread while searching for the undefined variable, the UndefinedImpl class pc.getThreadScope(key, _null) searches for the child threads and it returns the child thread if it exists, not thread scope.
