{"schema":"threatline.record/2","record":{"id":"CVE-2026-100694","aliases":["GHSA-pq74-mj4h-cjq2"],"summary":"Hugo before 0.166.0 Cross-Site Scripting via text/org","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 = ['.*'].","categories":["Unclassified"],"product":"hugo","vendor":"gohugoio","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100694","source_modified_at":"2026-09-30T15:05:16.280Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"hugo","vendor":"gohugoio","versions":[{"version":"0.56.0","status":"affected","versionType":"semver","lessThan":"0.166.0"},{"version":"0.166.0","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100694","source_modified_at":"2026-09-30T15:05:16.280Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"hugo","ecosystem":null},"version":"0.166.0","basis":"first unaffected version stated in the CVE record"}],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00188,"percentile":0.08018,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:23:52.256Z","modified_at":"2026-09-30T15:05:16.280Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100694","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T15:05:16.280Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100694","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/gohugoio/hugo/security/advisories/GHSA-pq74-mj4h-cjq2","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/hugo-before-0.166.0-cross-site-scripting-via-text-org","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-30T15:05:06.488369Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T15:05:16.280Z","content_hash":"955e4ecc4986e24e3c34db77f7ac2b74b9147c4252df0e57e1524c78f61a60fe"}}
