CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-45823 – Arbitrary file read in Artifact Hub
https://notcve.org/view.php?id=CVE-2023-45823
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. • https://artifacthub.io/packages/helm/artifact-hub/artifact-hub?modal=changelog&version=1.16.0 https://github.com/artifacthub/hub/security/advisories/GHSA-hmq4-c2r4-5q8h • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2023-45822 – Unsafe rego built-in allowed in Artifact Hub
https://notcve.org/view.php?id=CVE-2023-45822
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 a default unsafe rego built-in was allowed to be used when defining authorization policies. Artifact Hub includes a fine-grained authorization mechanism that allows organizations to define what actions can be performed by their members. It is based on customizable authorization policies that are enforced by the `Open Policy Agent`. Policies are written using `rego` and their data files are expected to be json documents. • https://artifacthub.io/packages/helm/artifact-hub/artifact-hub?modal=changelog&version=1.16.0 https://github.com/artifacthub/hub/security/advisories/GHSA-9pc8-m4vp-ggvf https://www.openpolicyagent.org https://www.openpolicyagent.org/docs/latest/#rego • CWE-918: Server-Side Request Forgery (SSRF) •
CVSS: 6.3EPSS: 0%CPEs: 1EXPL: 0CVE-2023-45821 – Incorrect Docker Hub registry check in Artifact Hub
https://notcve.org/view.php?id=CVE-2023-45821
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 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. • https://artifacthub.io/packages/helm/artifact-hub/artifact-hub?modal=changelog&version=1.16.0 https://github.com/artifacthub/hub/security/advisories/GHSA-g6pq-x539-7w4j • CWE-494: Download of Code Without Integrity Check •
