Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. 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 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](https://www.openpolicyagent.org/). Policies are written using [rego](https://www.openpolicyagent.org/docs/latest/#rego) and their data files are expected to be json documents. By default, `rego` allows policies to make HTTP requests, which can be abused to send requests to internal resources and forward the responses to an external entity. In the context of Artifact Hub, this capability should have been disabled. ### 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).
