CVE-2026-40153

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, the execute_command function in shell_tools.py calls os.path.expandvars() on every command argument at line 64, manually re-implementing shell-level environment variable expansion despite using shell=False (line 88) for security. This allows exfiltration of secrets stored in environment variables (database credentials, API keys, cloud access keys). The approval system displays the unexpanded $VAR references to human reviewers, creating a deceptive approval where the displayed command differs from what actually executes. This vulnerability is fixed in 1.5.128.

Summary		(es) PraisonAIAgents es un sistema de equipos multiagente. Antes de la versión 1.5.128, la función execute_command en shell_tools.py llama a os.path.expandvars() en cada argumento de comando en la línea 64, reimplementando manualmente la expansión de variables de entorno a nivel de shell a pesar de usar shell=False (línea 88) por seguridad. Esto permite la exfiltración de secretos almacenados en variables de entorno (credenciales de base de datos, claves de API, claves de acceso a la nube). El sistema de aprobación muestra las referencias $VAR sin expandir a los revisores humanos, creando una aprobación engañosa donde el comando mostrado difiere de lo que realmente se ejecuta. Esta vulnerabilidad se corrige en la versión 1.5.128.
