CVE-2023-29400

A flaw was found in golang. Templates containing actions in unquoted HTML attributes, for example, "attr={{.}}") executed with empty input, could result in output that has unexpected results when parsed due to HTML normalization rules. This issue may allow the injection of arbitrary attributes into tags.

For Red Hat Enterprise Linux,

• Conmon uses go in unit testing, but not functionally in the package. Go is used only in test files, not in the actual code. Thus, conmon is not affected.
• The Go templates in Grafana do not contain any javascript. Thus, it is not affected.
• Ignition does not make use of html/template.

In OpenShift Container Platform and Red Hat Advanced Cluster Management for Kubernetes (RHACM), the affected containers are behind OAuth authentication. This restricts access to the vulnerable golang html/templates to authenticated users, reducing the impact to low.
