Description Srikanth Balasubramanian 2026-09-11 06:08:25 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS.

Comment 1 mhorky 2026-10-20 11:31:52 UTC
html/template is not directly executed. This finding will autofix itself on the next rebuild. Closing as NOTABUG.
