Description
Hugo from v0.162.0 before v0.167.0 contains an improper link resolution vulnerability that lets malicious themes or modules expose files outside their root via nested-mount ancestor directories. Attackers controlling a theme can place a symlink or NTFS junction at a virtual ancestor directory, causing resources.Match to list and publish local files during builds.
