Any user able to execute arbitrary queries \u2014 including unauthenticated guests when --allow-guests is enabled \u2014 can use built-in string functions to construct a large string and pass it to the JavaScript runtime for compilation, triggering a null pointer dereference in the underlying QuickJS-NG engine. This causes the server process to terminate immediately without graceful shutdown, requiring a manual restart.
