From 4.0.0 until 4.7.10, Handlebars.precompile() uses quotedString() in lib/handlebars/compiler/code-gen.js to emit static template text into generated JavaScript without escaping sequences that terminate an enclosing HTML script element. When an application precompiles attacker-controlled template text and embeds the generated source directly in an inline script element, a closing script delimiter can end the element and cause following attacker-controlled markup to be parsed and executed. Ordinary server-side rendering and precompiled templates served as external JavaScript files are not affected. This issue is fixed in version 4.7.10.","state":0,"publishedAt":"2026-10-06T20:17:26.13+00:00","modifiedAt":"2026-10-07T13:58:29.527+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":4.7,"severity":"MEDIUM"}],"references":["https://github.com/handlebars-lang/handlebars.js/commit/609d1b11c833c9a3e00f56f2f34d22f425446725","https://github.com/handlebars-lang/handlebars.js/pull/2185","https://github.com/handlebars-lang/handlebars.js/releases/tag/v4.7.10","https://github.com/handlebars-lang/handlebars.js/security/advisories/GHSA-xw65-4hp5-5hc7"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-106444","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-116"],"productCriteria":[],"sourceDates":{"published":"2026-10-06T20:17:26.130","lastModified":"2026-10-07T13:58:29.527"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
