CVE-2026-108747
Lightdash hasta la versión 2.556.0 contiene una vulnerabilidad de omisión de autorización que permite que miembros autenticados de la organización eliminen los tokens de acceso personal de otros usuarios proporcionando su UUID. Los atacantes pueden enviar solicitudes DELETE a la ruta personal-access-tokens con el UUID del token de una víctima, incluso entre organizaciones, para revocarlo e interrumpir las integraciones de API.
