PraisonAI Code Execution Vulnerabilities

Arbitrary command and code execution in PraisonAI's workflow engine (versions <4.5.139) and praisonaiagents (<1.5.140) allows remote unauthenticated attackers to execute shell commands and Python code through malicious YAML workflow files. The vulnerability stems from unsafe processing of 'run:', 'script:', and 'python:' directives in job-type workflows without validation or sandboxing. With a critical CVSS score of 9.8 and network-accessible attack vector requiring no privileges or user interac

Arbitrary Python code execution in PraisonAI ≤4.5.138 occurs when malicious tools.py files are automatically imported from the current working directory without validation. Attackers placing a crafted tools.py in shared projects, cloned repositories, or writable workspaces achieve immediate code execution with full process privileges upon PraisonAI startup. EPSS data not available, but the local attack vector (AV:L) requiring no privileges (PR:N) or user interaction (UI:N) enables exploitation through supply chain and workspace poisoning attacks. No public exploit identified at time of analysis, though the vulnerability is trivial to exploit given the straightforward code injection mechanism.
