CVE-2026-4230Public exploitNetwork attack vector

Arbitrary SQL execution via unvalidated cache update

Published Mar 16, 2026 · Updated Mar 16, 2026

SQL injection in Vanna AI Vanna 2.0.0 through 2.0.2 allows remote attackers to execute arbitrary SQL against the connected database. The legacy Flask update_sql endpoint stores request-body SQL in the shared cache without validation, and run_sql executes that cached value. Default NoAuth exposure requires only network access and a valid cache identifier, enabling database reads, writes, or deletion under the configured database account.
