Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’) in praisonai_CVE-2026-40088

{
    "lastseen": "",
    "description": "PraisonAI is a multi-agent teams system. Prior to 4.5.121, the execute_command function and workflow shell execution are exposed to user-controlled input via agent workflows, YAML definitions, and LLM-generated tool calls, allowing attackers to inject arbitrary shell commands through shell metacharacters. This vulnerability is fixed in 4.5.121.",
