Vulnerability in praisonaiagents (CVE-2026-61437)

Summary

Vulnerability in praisonaiagents (CVE-2026-61437). Successful exploitation can lead to full system takeover. Exploitable via tools.py. Mitigation: upgrade to 1.6.78 or later.

Original description

The description as published by the source.

Summary

An unsafe dynamic module loading vulnerability allows an attacker who can control a workflow file and a sibling tools.py to execute arbitrary Python code when the workflow is executed.

Details

The vulnerability is located in the workflow structured output resolution logic.

File: src/praisonai-agents/praisonaiagents/workflows/workflows.py

Method: AgentFlow._resolve_pydantic_class

if self.file_path:
    workflow_dir = Path(self.file_path).parent
    tools_path = workflow_dir / "tools.py"

    if tools_path.exists():
        spec = importlib.util.spec_from_file_location("tools", tools_path)
        tools_module = importlib.util.module_from_spec(spec)
        spec.loader.exec_module(tools_module)   # Arbitrary code execution

This code is reached during step execution when a step uses a string output_pydantic:

step_output_pydantic = getattr(step, '_output_pydantic', None)
if step_output_pydantic and isinstance(step_output_pydantic, str):
    resolved_class = self._resolve_pydantic_class(step_output_pydantic)

file_path is set automatically by:

  • WorkflowManager._load_workflow() (used by workspace discovery)
  • WorkflowManager.create_workflow()

It can also be set manually after load_yaml():

wf = mgr.load_yaml("workflow.yaml")
wf.file_path = "workflow.yaml"

The exec_module() call has no sandboxing and ignores the PRAISONAI_ALLOW_*_TOOLS environment variables used elsewhere in the project.

❓ What is the problem

A vulnerability (CWE-693) exists in praisonaiagents. Attackers reach the vulnerable code path via tools.py without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of praisonaiagents. Attack surface: tools.py / output_pydantic / file_path / PRAISONAI_ALLOW_TEMPLATE_TOOLS.

🔥 Severity

Severity: High (CVSS 7.8/10). Successful exploitation can lead to full system takeover.

🔧 How to fix

Update to 1.6.78.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'praisonaiagents' . 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

  1. 1
    Identify exposure identify
    grep -r 'praisonaiagents' . | 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 praisonaiagents を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch
    Upgrade praisonaiagents to 1.6.78

    ステージング環境で 1.6.78 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を含めること。

  3. 3
    Post-deployment verification verify
    Confirm patched version is live in production

    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。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
