# CVE-2026-41496: PraisonAI: SQL Injection via unvalidated \`table\_prefix\` in 9 conversation store backends (incomplete fix for CVE-2026-40315)

- Also known as: GHSA-RG3H-X3JW-7JM5, PYSEC-2026-2923, PYSEC-2026-2952
- Severity: CVSS 8.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 4.5.149, 1.6.8
- Published: 2026-05-08 · Updated: 2026-05-08

## Affected

- MervinPraison PraisonAI: praisonaiagents \< 1.6.9, praisonai \< 4.6.9
- praisonai (PyPI): fixed in 4.5.149
- praisonaiagents (PyPI): fixed in 1.6.8

## Description

PraisonAI is a multi-agent teams system. Prior to praisonai version 4.6.9 and praisonaiagents version 1.6.9, the fix for CVE-2026-40315 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. This issue has been patched in praisonai version 4.6.9 and praisonaiagents version 1.6.9.
