EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.5 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 65% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

Hugo is a static site generator. From 0.123.0 to 0.161.1, a regression made  RootMappingFs.statRoot  use  Stat  (follows symlinks) instead of  Lstat , so a direct  resources.Get  of a symlink pointing outside its mount returned the target's contents — letting a symlink planted in a local mount (e.g. a vendored  themes/  theme) read arbitrary files accessible to the Hugo user. Go-module themes from GitHub (symlinks stripped) and directory walks were unaffected. Fixed in 0.162.0.
