An attacker could craft a malicious repository that, when cloned and opened in Theia, leads to execution of arbitrary commands with the user's privileges. In combination with AI chat features and a workspace .theia/settings.json that disabled tool confirmation, this could be triggered automatically by sending a message in the AI chat."},{"lang":"es","value":"En versiones de Eclipse Theia anteriores a la 1.69.0, las definiciones de tareas personalizadas en archivos de espacio de trabajo (p. ej., .theia/tasks.json, .vscode/tasks.json) podían ejecutarse sin requerir confianza del espacio de trabajo.
