CVE-2026-84061Public exploitNetwork attack vectorHinoki check available

Authenticated arbitrary SQL execution via fail-open validation

Published Sep 1, 2026 · Updated Sep 1, 2026

SQL injection in Yu Zhong OpenChatBI 0.3.0 and earlier allows remote authenticated users to execute arbitrary SQL via crafted prompts. The _validate_sql_safety function checks a limited denylist, then accepts unmatched LLM-generated SQL when the fail-closed guard is disabled by default. Access to text2sql is required; database permissions bound the ability to read, modify, or delete warehouse data.
