SCA: security update for PraisonAI, praisonaiagents (GHSA-vc46-vw85-3wvm)

critical Tenable Self-Hosted Container Security Plugin ID 440416

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PraisonAI is a multi-agent teams system. In versions below 4.5.139 of PraisonAI and 1.5.140 of
 praisonaiagents, the workflow engine is vulnerable to arbitrary command and code execution through
 untrusted YAML files. When praisonai workflow run <file.yaml> loads a YAML file with type: job, the
 JobWorkflowExecutor in job_workflow.py processes steps that support run: (shell commands via
 subprocess.run()), script: (inline Python via exec()), and python: (arbitrary Python script execution)—all
 without any validation, sandboxing, or user confirmation. The affected code paths include action_run() in
 workflow.py and _exec_shell(), _exec_inline_python(), and _exec_python_script() in job_workflow.py. An
 attacker who can supply or influence a workflow YAML file (particularly in CI pipelines, shared
 repositories, or multi-tenant deployment environments) can achieve full arbitrary command execution on the
 host system, compromising the machine and any accessible data or credentials. This issue has been fixed in
 versions 4.5.139 of PraisonAI and 1.5.140 of praisonaiagents. (CVE-2026-40288)

Solution

Update the praisonaiagents library and its related packages to version 1.5.140 or later.
