{"id":"CVE-2026-50135","aliases":["GHSA-fw87-fv5r-9fpw","GO-2026-5380"],"url":"https://o3.security/vulnerability/CVE-2026-50135","summary":"Hugo: Symlink confinement bypass in resources.Get","details":"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.","published":"2026-07-06T19:52:04.561Z","modified":"2026-08-12T03:51:40.509266394Z","cvss":null,"epss":{"score":0.00271,"percentile":0.19489,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/gohugoio/hugo","fixedVersion":"0.162.0"}],"fix":{"url":"https://github.com/gohugoio/hugo/commit/f8b5fa09a64950c32b803821ede411ebfe772b7a","label":"gohugoio/hugo@f8b5fa0"},"references":[{"type":"WEB","url":"https://github.com/gohugoio/hugo/releases/tag/v0.162.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50135.json"},{"type":"ADVISORY","url":"https://github.com/gohugoio/hugo/security/advisories/GHSA-fw87-fv5r-9fpw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50135"},{"type":"FIX","url":"https://github.com/gohugoio/hugo/commit/f8b5fa09a64950c32b803821ede411ebfe772b7a"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:40.509266394Z"}}
