Data deletion and disclosure via metadata SQL injection
Published May 29, 2026 · Updated May 29, 2026
SQL injection in Agno 2.6.5 allows remote authenticated users to delete or disclose ClickHouse vector data through metadata input. The delete_by_metadata() method in clickhousedb.py inserts metadata keys and values directly into a DELETE WHERE clause with f-strings instead of binding or escaping them. The caller must control metadata passed to the method; injected predicates can target selected rows or the entire table, while error-based or blind techniques can disclose data.
