CVE-2026-44691

In Eclipse Theia versions prior to 1.69.0, custom task definitions in workspace files (e.g. .theia/tasks.json, .vscode/tasks.json) could be executed without requiring workspace trust. 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.

Summary		(es) 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. Un atacante podría diseñar un repositorio malicioso que, al ser clonado y abierto en Theia, lleva a la ejecución de comandos arbitrarios con los privilegios del usuario. En combinación con las funciones de chat de IA y un archivo .theia/settings.json del espacio de trabajo que deshabilitaba la confirmación de herramientas, esto podría activarse automáticamente al enviar un mensaje en el chat de IA.
