Descriptions

In all versions of GitLab CE/EE since version 8.0, an attacker can set the pipeline schedules to be active in a project export so when an unsuspecting owner imports that project, pipelines are active by default on that project. Under specialized conditions, this may lead to information disclosure if the project is imported from an untrusted source.

En todas las versiones de GitLab CE/EE desde versión 8.0, un atacante puede configurar las programaciones de tuberías para que estén activas en una exportación de proyectos, de modo que cuando un propietario desprevenido importa ese proyecto, las tuberías están activas por defecto en ese proyecto. Bajo condiciones especializadas, esto puede conllevar a una divulgación de información si el proyecto es importado desde una fuente no confiable
