Vulnerability in PraisonAI (CVE-2026-47398)
Summary
Vulnerability in PraisonAI (CVE-2026-47398). Successful exploitation can lead to full system takeover. Exploitable via POST /v1/recipes/run. Mitigation: upgrade to 4.6.40 or later.
Original description
The description as published by the source.
Arbitrary code execution via ungated spec.loader.exec_module in agents_generator.py (v4.6.32 chokepoint refactor bypass)
Summary
The v4.6.32 chokepoint refactor (which patched CVE-2026-44334 / GHSA-xcmw-grxf-wjhj) added the PRAISONAI_ALLOW_LOCAL_TOOLS env-var gate to the tool_override.py sinks. However, two additional spec.loader.exec_module call sites in praisonai/agents_generator.py were missed and remain completely unguarded on current master (v4.6.37). Both functions accept a module_path parameter sourced from YAML configuration and execute it without validation, signature checking, or the env-var gate.
Patch lineage
| CVE | GHSA | Fixed in | What was patched |
|---|---|---|---|
| CVE-2026-40156 | GHSA-2g3w-cpc4-chr4 | 4.5.128 | CWD tools.py auto-load in tool_resolver.py |
| CVE-2026-40287 | GHSA-g985-wjh9-qxxc | 4.5.139 | Env-var gate added to tool_resolver.py + api/call.py |
| CVE-2026-44334 | GHSA-xcmw-grxf-wjhj | 4.6.32 | Missed sink in templates/tool_override.py |
| This finding | — | unfixed | Missed sinks in agents_generator.py |
Every prior patch addressed a subset of exec_module call sites. The two sinks documented here were present throughout the entire fix sequence and remain unpatched.

CVE-2026-47398 (PraisonAI) — CWE-829 / CVSS v3 8.1
Attack vector: remote (network-reachable) / unauthenticated / no user interaction
Attack surface: POST /v1/recipes/run / spec.loader.exec_module / agents_generator.py / PRAISONAI_ALLOW_LOCAL_TOOLS
Patched: 4.6.40 — apply immediately
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
A vulnerability (CWE-829) exists in PraisonAI. Attackers reach the vulnerable code path via POST /v1/recipes/run without authentication.
Check the vendor advisory for the affected versions of PraisonAI. Attack surface: POST /v1/recipes/run / spec.loader.exec_module / agents_generator.py / PRAISONAI_ALLOW_LOCAL_TOOLS.
Severity: High (CVSS 8.1/10). Successful exploitation can lead to full system takeover.
Update to 4.6.40.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual POST /v1/recipes/run requests with malformed payloads or SQL meta-characters. Run grep -r 'PraisonAI' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response actions
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'PraisonAI' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
PraisonAIを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'POST /v1/recipes/run' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
POST /v1/recipes/runへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Apply patch patch
Upgrade PraisonAI to 4.6.40ステージング環境で 4.6.40 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 2 で見つけた異常検知の続報チェックを含めること。
-
4Post-deployment verification verify
Replay attack against POST /v1/recipes/run on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
