{"id":"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.","aliases":["GHSA-fw87-fv5r-9fpw","GO-2026-5380"],"modified":"2026-07-09T03:51:49.134414549Z","published":"2026-07-06T19:52:04.561Z","database_specific":{"cwe_ids":["CWE-59"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50135.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gohugoio/hugo","events":[{"introduced":"3c8a4713908e48e6523f058ca126710397aa4ed5"},{"fixed":"f8b5fa09a64950c32b803821ede411ebfe772b7a"},{"fixed":"076dfe13d0f789e3d9586b192f8f7f3329c26990"}],"database_specific":{"extracted_events":[{"introduced":"0.123.0"},{"fixed":"0.162.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50135.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
