Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PraisonAI 是一个多智能体团队协作系统。在 4.5.87 版本至 4.6.61 版本之前（不含 4.6.61），PraisonAI 的配方（recipe）执行机制中存在一项危险工具策略：该策略本应默认拒绝所有未明确允许的危险工具，除非调用方显式传入 。然而，该策略仅检查 中 字段所声明的工具。 对于基于步骤（steps-based）的配方，实际执行路径会加载 文件，并由 解析。该解析器会解析智能体级别（agent-level）的 声明，并保留顶层的 配置。随后， 方法会将这些通过 YAML 批准的工具安装到

Vulnerability Title
PraisonAI recipe workflow policy can be bypassed by declaring and YAML-approving dangerous tools outside TEMPLATE.yaml
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. From version 4.5.87 to before version 4.6.61, PraisonAI recipe execution has a dangerous-tool policy that is supposed to block default-denied tools unless the caller explicitly passes allow_dangerous_tools=True. That policy only checks tools declared in TEMPLATE.yaml requires.tools. For steps-based recipes, the actual execution path loads workflow.yaml with YAMLWorkflowParser. That parser resolves agent-level tools: declarations and preserves top-level approve:. Workflow.start() then installs those YAML-approved tools into the approval context. As a result, an untrusted recipe can omit execute_command from TEMPLATE.yaml requires.tools, declare it in workflow.yaml agents.*.tools, and add top-level approve: [execute_command]. The caller did not set allow_dangerous_tools=True, but the recipe policy allows the recipe and the workflow approval path self-approves the critical shell tool. This issue has been patched in version 4.6.61.
