What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Hugo before v0.167.0 contains a path traversal vulnerability in css.Sass that allows malicious themes or modules to read files outside the project root through the Sass compiler's import fallback. Attackers can ship stylesheets with relative, absolute, or symlinked @import or @use targets to compile readable files into the published site CSS.
