CVE-2026-75859

CodeWhale versions before 0.8.64 fail to validate file paths in the project config instructions field, allowing attackers to read arbitrary files on the victim's system. A malicious .codewhale/config.toml file in a cloned repository can specify paths outside the workspace that are read and injected into the AI system prompt for exfiltration.

Summary		(es) Versiones de CodeWhale anteriores a la 0.8.64 fallan al validar las rutas de archivo en el campo de instrucciones de configuración del proyecto, permitiendo a los atacantes leer archivos arbitrarios en el sistema de la víctima. Un archivo .codewhale/config.toml malicioso en un repositorio clonado puede especificar rutas fuera del espacio de trabajo que son leídas e inyectadas en el prompt del sistema de IA para exfiltración.
