Descriptions

Artifact Hub is a web-based application that enables finding, installing, and publishing packages and configurations for CNCF projects. During a security audit of Artifact Hub's code base a security researcher identified a bug in which by using symbolic links in certain kinds of repositories loaded into Artifact Hub, it was possible to read internal files. Artifact Hub indexes content from a variety of sources, including git repositories. When processing git based repositories, Artifact Hub clones the repository and, depending on the artifact kind, reads some files from it. During this process, in some cases, no validation was done to check if the file was a symbolic link. This made possible to read arbitrary files in the system, potentially leaking sensitive information. This issue has been resolved in version `1.16.0`. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Artifact Hub es una aplicación basada en web que permite buscar, instalar y publicar paquetes y configuraciones para proyectos CNCF. Durante una auditoría de seguridad del código base de Artifact Hub, un investigador de seguridad identificó un error en el que, mediante el uso de enlaces simbólicos en ciertos tipos de repositorios cargados en Artifact Hub, era posible leer archivos internos. Artifact Hub indexa contenido de una variedad de fuentes, incluidos repositorios de git. Al procesar repositorios basados en git, Artifact Hub clona el repositorio y, según el tipo de artefacto, lee algunos archivos del mismo. Durante este proceso, en algunos casos, no se realizó ninguna validación para verificar si el archivo era un enlace simbólico. Esto hizo posible leer archivos arbitrarios en el system, potencialmente filtrando información confidencial. Este problema se resolvió en la versión `1.16.0`. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
