Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/openshift-update-service/openshift-update-service-rhel8, Red Hat/quay/quay-rhel8, Red Hat/quay/quay-rhel9.
  2. 2Review the reported fix. Source-reported workaround: To mitigate this issue, disable the `FEATURE_BUILD_SUPPORT` feature in Red Hat Quay if it is not essential for your operations. This action prevents the vulnerable build API endpoint from being exploited. Refer to the Red Hat Quay product documentation for detailed instructions on managing and disabling features.

Upstream source description

A flaw was found in Red Hat Quay. A user with FEATURE_BUILD_SUPPORT enabled and repository write access can exploit a Server-Side Request Forgery (SSRF) vulnerability within the build API. This allows the user to provide a malicious URL, causing the Quay builder to make requests to internal network addresses. Such an action could lead to the disclosure of sensitive internal information.
