Technical details
The queryById handler in AiragAppController lacks @RequiresPermissions annotation and does not validate that the requesting user owns the queried application, despite all other handlers in the same controller having authorization checks. An authenticated attacker can enumerate application IDs via the unguarded /airag/app/listDict endpoint and subsequently query any ID to retrieve complete AiragApp objects containing system prompts, model IDs, knowledge base IDs, memory configuration, plugin bindings, and share tokens from other users' deployments.
