{"id":"DEBIAN-CVE-2026-89259","details":"Hugo is a static site generator. From v0.161.0, Hugo executes Node tools under Node's permission model, but TailwindCSS — included in the default security.exec.allow list — requires a highly permissive configuration (--allow-addons, --allow-child-process, --allow-worker). As a result, the restrictions intended by the fix for GHSA-x597-9fr4-5857 could still be bypassed, allowing a Node tool invoked during a build to read and write files outside the project's working directory. Affected versions are those after v0.43; the issue was fixed in v0.165.0 by removing tailwindcss from the default security.exec.allow list. Users who do not use TailwindCSS, or who only build trusted sites, are not affected. As a workaround, users can define a restrictive security.exec.allow list in hugo.toml.","modified":"2026-09-25T08:47:24.669667859Z","published":"2026-09-11T12:16:56.480Z","upstream":["CVE-2026-89259"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-89259"}],"affected":[{"package":{"name":"hugo","ecosystem":"Debian:14","purl":"pkg:deb/debian/hugo?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.165.0-1"}]}],"versions":["0.131.0-1","0.131.0-2","0.150.0-1","0.150.1-1","0.151.0-1","0.151.1-1","0.151.2-1","0.152.1-1","0.152.2-1","0.153.0-1","0.153.1-1","0.153.1-2","0.153.1-3","0.153.2-1","0.154.1-1","0.154.2-1","0.154.2-2","0.154.3-1","0.154.5-1","0.155.1-1","0.155.2-1","0.155.3-1","0.157.0-1","0.157.0-2","0.157.0-3","0.158.0-1","0.158.0-2","0.158.0-3","0.159.0-1","0.159.1-1","0.159.2-1","0.160.0-1","0.160.0-2","0.160.1-1","0.161.0-1","0.161.1-1","0.162.1-1","0.162.1-2","0.162.1-3","0.162.1-4","0.162.1-5","0.162.1-6","0.162.1-7"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-89259.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
