CVE-2026-61437
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPraisonAI (pip package praisonaiagents) before 1.6.78 contains an unsafe dynamic module loading vulnerability in AgentFlow._resolve_pydantic_class (src/praisonai-agents/praisonaiagents/workflows/workflows.py). When a workflow step uses a string output_pydantic reference, the framework locates and imports a sibling tools.py from the workflow file's directory via importlib exec_module without sandboxing, ignoring the PRAISONAI_ALLOW_*_TOOLS environment variables. An attacker who controls a workflow file and its sibling tools.py can execute arbitrary Python code with the workflow runner's privileges when the workflow is executed via WorkflowManager or after load_yaml.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencePraisonAI before 1.6.78 has an unsafe dynamic module loading vulnerability in AgentFlow._resolve_pydantic_class. The method imports a sibling tools.py from the workflow file's directory using importlib.exec_module without sandboxing when resolving string output_pydantic references, ignoring security environment variables. An attacker who controls both a workflow file and its sibling tools.py can achieve arbitrary code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed PraisonAI versionRun: pip show praisonaiagents or pip show praisonai | grep VersionAffected if Version is before 1.6.78 (e.g., 1.6.77, 1.6.0, etc.)
-
Locate AgentFlow._resolve_pydantic_class methodSearch for the method in the installed package: find $(python -c 'import praisonaiagents; print(praisonaiagents.__path__[0])') -name '*.py' -exec grep -l '_resolve_pydantic_class' {} \;Affected if The method exists and uses importlib.exec_module without sandboxing on workflow file directories
-
Identify workflow file usageCheck if your application loads workflow YAML/JSON files that reference pydantic models via AgentFlow (search for workflow file loading or agent execution patterns)Affected if Your application loads workflow files that trigger the _resolve_pydantic_class method for string output_pydantic references
-
Assess directory write accessReview file permissions on directories containing workflow files and any sibling tools.py files: ls -la /path/to/workflow/directory/Affected if Untrusted users can write to directories containing workflow files that also contain or could contain a tools.py
You are affected if praisonaiagents version is below 1.6.78 AND your environment loads workflow files that trigger the vulnerable _resolve_pydantic_class method, especially if workflow directories are writable by untrusted users who could supply a malicious tools.py.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade praisonaiagents to version 1.6.78 or later. Until then, ensure workflow files and their directories are not writable by untrusted users.
praisonaiagents version 1.6.78 or later
- Check current installed version: pip show praisonaiagents
- Upgrade to version 1.6.78 or later: pip install --upgrade praisonaiagents>=1.6.78
- Verify the installed version: pip show praisonaiagents
- If using in code, ensure WorkflowManager or load_yaml is called only on trusted workflow files
