  "details": "ScriptTriggerExecutor sets allowedPackages to java.lang.*, java.util.*, java.time.*, java.math.* (ScriptTriggerExecutor.java:56); trigger creation is gated only at UPDATE_SCHEMA (LocalSchema.createTrigger:636). Permitting java.lang.* host-class lookup lets a trigger script do Java.type(\"java.lang.Runtime\").getRuntime().exec(...) (or ProcessBuilder). The reflection denylist does not block Java.type host lookups, and allowCreateProcess(false) only restricts GraalVM\u0027s guest process API, not a host Runtime.exec reached through HostAccess.ALL.\n\nExploit: a user with UPDATE_SCHEMA (schema admin, strictly less than security admin) runs CREATE TRIGGER ... EXECUTE JAVASCRIPT \u0027\u003cruntime.exec\u003e\u0027 and obtains OS RCE when the trigger fires.\n\nFix: remove java.lang.* (and narrow the rest) from the trigger allow-list; if host interop is needed, expose an explicit @HostAccess.Export API surface instead of whole packages; consider gating trigger creation at UPDATE_SECURITY. Prefer an allow-list (HostAccess.EXPLICIT) over the current denylist-over-HostAccess.ALL.\n\nRelated medium/low items to fold into the fix: IMPORT DATABASE SSRF via unfollowed-redirect re-validation (SourceDiscovery.java:113), BACKUP/EXPORT DATABASE missing authorization (BackupDatabaseStatement.java:56, ExportDatabaseStatement.java:52), chunked-transfer body-size DoS bypass (HttpServer.java:301,318-333), and no brute-force lockout on password auth (ServerSecurity.java:189-205).",
