{"id":"DEBIAN-CVE-2026-100694","details":"Hugo is a static site generator. In versions from v0.56.0 through v0.165.x, content files mapped to the text/org media type are rendered without escaping raw HTML: Org export blocks and @@html:...@@ snippets pass HTML through unescaped, resulting in cross-site scripting (XSS) in the generated site. An attacker who can supply or influence a content file under /content or the output of a content adapter can inject scripts that execute in the browsers of visitors to the affected pages. Only pages whose source file or content-adapter output declares the text/org media type are affected, and sites that fully trust all content sources are not impacted. Version v0.166.0 fixes the issue by introducing a security.allowContent allowlist that denies text/org by default; sites that intentionally author Org Mode content can opt back in with [security] allowContent = ['.*'].","modified":"2026-09-27T05:00:06.688162470Z","published":"2026-09-26T14:16:54.150Z","upstream":["CVE-2026-100694"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-100694"}],"affected":[{"package":{"name":"hugo","ecosystem":"Debian:12","purl":"pkg:deb/debian/hugo?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.111.3-1","0.112.7-1","0.113.0-1","0.113.0-2","0.113.0-3","0.114.1-1","0.114.1-2","0.115.4-1","0.116.1-1","0.117.0-1","0.118.2-1","0.119.0-1","0.119.0-2","0.120.3-1","0.120.4-1","0.121.1-1","0.121.2-1","0.122.0-1","0.123.3-1","0.123.7-1","0.123.8-1","0.123.8-2","0.124.1-1","0.125.4-1","0.125.5-1","0.125.6-1","0.125.7-1","0.126.1-1","0.126.2-1","0.126.3-1","0.127.0-1","0.128.2-1","0.128.2-2","0.129.0-1","0.129.0-2","0.130.0-1","0.130.0-2","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","0.165.0-1","0.165.0-2","0.165.0-3","0.166.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100694.json"}},{"package":{"name":"hugo","ecosystem":"Debian:13","purl":"pkg:deb/debian/hugo?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"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","0.165.0-1","0.165.0-2","0.165.0-3","0.166.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100694.json"}},{"package":{"name":"hugo","ecosystem":"Debian:14","purl":"pkg:deb/debian/hugo?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"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","0.165.0-1","0.165.0-2","0.165.0-3","0.166.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100694.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
