This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from artifacthub. Update hub to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
