github.com/artifacthub/hub fixed: 1.16.0 
Upgrade github.com/artifacthub/hub to 1.16.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/artifacthub/hub

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-45821, inspect your project dependencies for Github.com/artifacthub/hub:

inspect dependencies for github.com/artifacthub/hub

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-494: Download of Code Without Integrity Check, where the product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code. In Github.com/artifacthub/hub, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact During a security audit of Artifact Hub's code base, a security researcher at [OffSec](https://www.offsec.com/) identified a bug in which the `registryIsDockerHub` function was only checking that the registry domain had the `docker.io` suffix. Artifact Hub allows providing some Docker credentials that are used to increase the rate limit applied when interacting with the Docker Hub registry API to read publicly available content. Due to the incorrect check described above, it'd be possible to hijack those credentials by purchasing a domain which ends with `docker.io` and deploying a fake OCI registry on it. <https://artifacthub.io/> uses some credentials that only have permissions to read public content available in the Docker Hub. However, even though credentials for private repositories (disabled on `artifacthub.io`) are handled in a different way, other Artifact Hub deployments could have been using them for a different purpose. ### Patches This issue has been resolved in version [1.16.0](https://artifacthub.io/packages/helm/artifact-hub/artifact-hub?modal=changelog&version=1.16.0).
