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.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
