Name of the Vulnerable Software and Affected Versions
Artifact Hub versions prior to 1.16.0
Description
Artifact Hub is a web-based application that enables finding, installing, and publishing packages and configurations for CNCF projects. 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.
Recommendations
For versions prior to 1.16.0, upgrade to version 1.16.0 to resolve the issue. As a temporary workaround, consider restricting access to the git repositories processed by Artifact Hub to minimize the risk of exploitation. Avoid using symbolic links in repositories loaded into Artifact Hub until the issue is resolved.
