      "value": "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."

      "value": "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."
