{"id":"CVE-2026-44301","summary":"Hugo: Node tool execution allows file system access outside the project directory","details":"Hugo is a static site generator. From 0.43 to before 0.161.0, when building a Hugo site that uses Node-based asset pipelines (PostCSS, Babel, TailwindCSS), Hugo invoked the configured Node tools without restrictions on file system access. As a result, executing hugo against an untrusted site could allow code running through these tools to read or write files outside the project's working directory. Users who do not use PostCSS, Babel, or TailwindCSS, or who only build trusted sites, are not affected. This vulnerability is fixed in 0.161.0.","aliases":["GHSA-x597-9fr4-5857","GO-2026-5740"],"modified":"2026-10-28T02:33:07.601068438Z","published":"2026-05-12T21:37:52.825Z","related":["SUSE-SU-2026:23216-1","SUSE-SU-2026:23227-1","openSUSE-SU-2026:21551-1"],"database_specific":{"cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44301.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44301.json"},{"type":"ADVISORY","url":"https://github.com/gohugoio/hugo/security/advisories/GHSA-x597-9fr4-5857"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44301"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gohugoio/hugo","events":[{"introduced":"cbb7214b6c54c24193dee8a284cfcab6b4951b46"},{"fixed":"98d396c16a07b51df06e7673d817a3880da6218d"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0.43.0"},{"fixed":"0.161.0"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"cpe":"cpe:2.3:a:gohugo:hugo:*:*:*:*:*:*:*:*","range":[{"introduced":"0.43"},{"fixed":"0.161.0"}],"source":"CPE_RANGE"}]}}],"versions":["v0.160.1","v0.160.0","v0.159.2","v0.159.1","v0.159.0","v0.158.0","v0.157.0","v0.156.0","v0.155.3","v0.155.2","v0.155.1","v0.155.0","v0.154.5","v0.154.4","v0.154.3","v0.154.2","v0.154.1","v0.154.0","v0.153.5","v0.153.4","v0.153.3","v0.153.2","v0.153.1","v0.153.0","v0.152.2","v0.152.1","v0.152.0","v0.151.1","v0.151.0","v0.150.1","v0.150.0","v0.149.1","v0.149.0","v0.148.2","v0.148.1","v0.148.0","v0.147.9","v0.147.8","v0.147.7","v0.147.6","v0.147.5","v0.147.3","v0.147.2","v0.147.1","v0.147.0","v0.146.7","v0.146.6","v0.146.5","v0.146.4","v0.146.3","v0.146.2","v0.146.1","v0.146.0","v0.145.0","v0.144.1","v0.144.0","v0.143.1","v0.143.0","v0.142.0","v0.141.0","v0.140.2","v0.140.1","v0.140.0","v0.139.4","v0.139.3","v0.139.2","v0.139.1","v0.139.0","v0.138.0","v0.137.1","v0.137.0","v0.136.5","v0.136.3","v0.136.2","v0.136.1","v0.136.0","v0.135.0","v0.134.3","v0.134.2","v0.134.1","v0.134.0","v0.133.1","v0.133.0","v0.132.2","v0.132.1","v0.132.0","v0.131.0","v0.130.0","v0.129.0","v0.128.2","v0.128.1","v0.128.0","v0.127.0","v0.126.3","v0.126.1","v0.126.0","v0.125.7","v0.125.6","v0.125.5","v0.125.4","v0.125.2","v0.125.1","v0.125.0","v0.124.1","v0.124.0","v0.123.8","v0.123.7","v0.123.6","v0.123.5","v0.123.4","v0.123.3","v0.123.2","v0.123.1","v0.122.0","v0.121.2","v0.121.1","v0.121.0","v0.120.4","v0.120.3","v0.120.2","v0.120.1","v0.120.0","v0.119.0","v0.118.2","v0.118.1","v0.118.0","v0.116.1","v0.116.0","v0.115.4","v0.115.3","v0.115.2","v0.115.1","v0.115.0","v0.114.0","v0.113.0","v0.112.7","v0.112.6","v0.112.4","v0.112.3","v0.112.2","v0.112.1","v0.112.0","v0.111.3","v0.111.2","v0.111.1","v0.110.0","v0.109.0","v0.108.0","v0.107.0","v0.106.0","v0.105.0","v0.104.3","v0.104.2","v0.104.1","v0.104.0","v0.103.1","v0.102.3","v0.102.0","v0.101.0","v0.100.2","v0.100.1","v0.100.0","v0.99.1","v0.99.0","v0.98.0","v0.97.3","v0.97.2","v0.97.1","v0.97.0","v0.95.0","v0.94.2","v0.94.1","v0.94.0","v0.93.3","v0.93.2","v0.93.1","v0.93.0","v0.92.2","v0.92.1","v0.92.0","v0.91.2","v0.91.1","v0.91.0","v0.90.1","v0.90.0","v0.89.4","v0.89.3","v0.89.2","v0.89.1","v0.89.0","v0.88.1","v0.88.0","v0.87.0","v0.86.0","v0.85.0","v0.84.4","v0.84.3","v0.84.2","v0.84.1","v0.84.0","v0.83.1","v0.83.0","v0.82.0","v0.81.0","v0.80.0","v0.79.0","v0.78.2","v0.78.1","v0.78.0","v0.77.0","v0.76.4","v0.76.2","v0.76.1","v0.76.0","v0.75.1","v0.75.0","v0.74.3","v0.74.2","v0.74.1","v0.74.0","v0.72.0","v0.71.1","v0.71.0","v0.70.0","v0.69.2","v0.69.1","v0.69.0","v0.68.3","v0.68.2","v0.68.1","v0.68.0","v0.67.1","v0.67.0","v0.66.0","v0.65.3","v0.65.2","v0.65.1","v0.65.0","v0.64.1","v0.64.0","v0.63.2","v0.63.1","v0.63.0","v0.62.2","v0.62.1","v0.62.0","v0.61.0","v0.60.1","v0.60.0","v0.59.1","v0.59.0","v0.58.3","v0.58.2","v0.58.1","v0.58.0","v0.57.2","v0.57.1","v0.57.0","v0.56.3","v0.56.2","v0.56.0","v0.55.5","v0.55.4","v0.55.3","v0.55.2","v0.55.1","v0.55.0","v0.54.0","v0.53","v0.52","v0.51","v0.50","v0.49","v0.48","v0.47.1","v0.47","v0.46","v0.45.1","v0.45","v0.44","v0.43"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-44301.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U"}]}
