CVE-2026-44301

Hugo: Node tool execution allows file system access outside the project directory

Published May 12, 2026 CVSS 4.0 · 6.2 Medium EPSS < 1% KEV · Not listed
Description
Hugo is a static site generator. From 0.43 to before 0.161.0, when building a Hugo site that uses Node-based asset pipelines (PostCSS, Babel, TailwindCSS), Hugo invoked the configured Node tools without restrictions on file system access. As a result, executing hugo against an untrusted site could allow code running through these tools to read or write files outside the project's working directory. Users who do not use PostCSS, Babel, or TailwindCSS, or who only build trusted sites, are not affected. This vulnerability is fixed in 0.161.0.
