CVE-2026-50133

Hugo: XSS via text/html content files

Published Jul 6, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
Hugo is a static site generator. Prior to 0.162.0, Hugo accepts content files in several markup formats. Files mapped to the text/html media type (typically .html files under /content, or pages produced by a content adapter that sets content.mediaType = "text/html") had their body emitted verbatim into the rendered page. A site that ingests HTML content from an untrusted source could therefore be served stored cross-site scripting. This vulnerability is fixed in 0.162.0.
