How do I detect CVE-2024-55601 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gohugoio/hugo, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-55601 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2024-55601 actively exploited in the wild?

Description

Hugo is a static site generator. Starting in version 0.123.0 and prior to version 0.139.4, some HTML attributes in Markdown in the internal templates listed below not escaped in internal render hooks. Those whoa re impacted are Hugo users who do not trust their Markdown content files and are using one or more of these templates: _default/_markup/render-link.html from v0.123.0; _default/_markup/render-image.html from v0.123.0; _default/_markup/render-table.html from v0.134.0; and/or shortcodes/youtube.html from v0.125.0. This issue is patched in v0.139.4. As a workaround, one may replace an affected component with user defined templates or disable the internal templates.
