Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Mervin Praison PraisonAI是Mervin Praison个人开发者开源的一个低代码多智能体协作框架。 Mervin Praison PraisonAI 4.6.40之前版本存在安全漏洞，该漏洞源于praisonai/agents_generator.py中缺失了对spec.loader.exec_module调用站点的验证，允许从YAML配置获取的module_path参数未经验证、签名检查或环境变量门控直接执行，可能导致代码注入。

Vulnerability Title
PraisonAI: Arbitrary code execution via unguarded `spec.loader.exec_module` in `agents_generator.py` - sibling of CVE-2026-44334
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. The v4.6.32 chokepoint refactor (which patched CVE-2026-44334 / GHSA-xcmw-grxf-wjhj) added the PRAISONAI_ALLOW_LOCAL_TOOLS env-var gate to the tool_override.py sinks. However, two additional spec.loader.exec_module call sites in praisonai/agents_generator.py were missed and remain completely unguarded in versions prior to 4.6.40. Both functions accept a module_path parameter sourced from YAML configuration and execute it without validation, signature checking, or the env-var gate. Version 4.6.40 fixes the issue.
