This flaw could allow attackers to inject malicious scripts into web pages, potentially leading to arbitrary code execution in users' browsers. The advisory references Red Hat Hardened Images RPMs version 0.163.3-0.1.hum1 as affected. No explicit patch version is stated as fixed in the advisory, and no known exploits are reported in the wild. The severity is assessed as medium.

0 Hugo is a static site generator. From 0.60.0 until 0.163.3, Hugo's default code-block renderer wrote the Markdown code-fence language or info-string into the code class="language-…" data-lang="…" wrapper without HTML escaping. A fence info-string containing a quote and a script payload breaks out of the attribute and injects a live script element. This issue is fixed in 0.163.3.
