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":"2026-10-06T19:01:14.626+00:00","modifiedAt":"2026-10-06T19:48:02.05+00:00","affected":[{"ecosystem":"Vendor product","name":"handlebars.js","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"handlebars-lang\",\n                    \"product\": \"handlebars.js\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.0.0, < 4.7.10\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-xw65-4hp5-5hc7","https://github.com/handlebars-lang/handlebars.js/pull/2185","https://github.com/handlebars-lang/handlebars.js/commit/609d1b11c833c9a3e00f56f2f34d22f425446725","https://github.com/handlebars-lang/handlebars.js/releases/tag/v4.7.10"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106444","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106444","identifiers":["CVE-2026-106444"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
