The record
The fix for [CVE-2026-40315](https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-x783-xp3g-mqhp) added input validation to `SQLiteConversationStore` only. Nine sibling backends — MySQL, PostgreSQL, async SQLite/MySQL/PostgreSQL, Turso, SingleStore, Supabase, SurrealDB — pass `table_prefix` straight into f-string SQL. Same root cause, same code pattern, same exploitation. 52 unvalidated injection points across the codebase. `postgres.py` additionally accepts an unvalidated `schema` parameter used directly in DDL.
