From 3.0.0 until 4.7.10, Handlebars lookupProperty returns Function.prototype.constructor before applying the prototype-access deny list because constructor is an own property of Function.prototype. When an attacker can render a controlled template with allowProtoMethodsByDefault enabled and an accessible function in the template context, the template can traverse from that function through its prototype to Function.prototype and then obtain the Function constructor through the own-property bypass. This permits attacker-controlled JavaScript to execute with the server application's privileges. This issue is fixed in version 4.7.10.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2,"severity":null}],"references":["https://github.com/handlebars-lang/handlebars.js/security/advisories/GHSA-p8wg-vrv2-v86f","https://github.com/handlebars-lang/handlebars.js/pull/2185","https://github.com/handlebars-lang/handlebars.js/commit/ceec388abe1d1aac8f6369860d5f390fa71ef4fa","https://github.com/handlebars-lang/handlebars.js/releases/tag/v4.7.10"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-93952","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 6, 2026, 7:39:08 PM","dateUpdated":"Oct 12, 2026, 2:33:33 PM"},"relatedAdvisories":[{"id":"RHSA-2026:92307","title":"Red Hat Security Advisory: Red Hat Advanced Cluster Management for Kubernetes v2.13.14 security update","vulnerabilityIds":["CVE-2026-14199","CVE-2026-15815","CVE-2026-33818","CVE-2026-37236","CVE-2026-39834","CVE-2026-56853","CVE-2026-56854","CVE-2026-56858","CVE-2026-56859","CVE-2026-56860","CVE-2026-56862","CVE-2026-63209","CVE-2026-77354","CVE-2026-77405","CVE-2026-77411","CVE-2026-84304","CVE-2026-84375","CVE-2026-84445","CVE-2026-88031","CVE-2026-93748","CVE-2026-106445","CVE-2026-106446"]},{"id":"RHSA-2026:92510","title":"Red Hat Security Advisory: RHOAI 3.4.6 - Red Hat OpenShift AI","vulnerabilityIds":["CVE-2023-54404","CVE-2026-11822","CVE-2026-11824","CVE-2026-13717","CVE-2026-16221","CVE-2026-17106","CVE-2026-18446","CVE-2026-25681","CVE-2026-26007","CVE-2026-27136","CVE-2026-33814","CVE-2026-33818","CVE-2026-39821","CVE-2026-39834","CVE-2026-41178","CVE-2026-42502","CVE-2026-45819","CVE-2026-45820","CVE-2026-56853","CVE-2026-56858","CVE-2026-56859","CVE-2026-56860","CVE-2026-56862","CVE-2026-57516","CVE-2026-59951","CVE-2026-63209","CVE-2026-63374","CVE-2026-65898","CVE-2026-67312","CVE-2026-67314","CVE-2026-67320","CVE-2026-67321","CVE-2026-69097","CVE-2026-69153","CVE-2026-73086","CVE-2026-73088","CVE-2026-73089","CVE-2026-73643","CVE-2026-75838","CVE-2026-75899","CVE-2026-75931","CVE-2026-75975","CVE-2026-76172","CVE-2026-76844","CVE-2026-77301","CVE-2026-78679","CVE-2026-82397","CVE-2026-83663","CVE-2026-84375","CVE-2026-84445","CVE-2026-85393","CVE-2026-85525","CVE-2026-87018","CVE-2026-90711","CVE-2026-91990","CVE-2026-92599","CVE-2026-93690","CVE-2026-93749","CVE-2026-94637","CVE-2026-96640","CVE-2026-96643","CVE-2026-96644","CVE-2026-96778","CVE-2026-96804","CVE-2026-97687","CVE-2026-97689","CVE-2026-102267","CVE-2026-102271","CVE-2026-102272","CVE-2026-102276","CVE-2026-102278","CVE-2026-102282","CVE-2026-104150","CVE-2026-104851","CVE-2026-105922","CVE-2026-106445","CVE-2026-106446","CVE-2026-109156","CVE-2026-109383","CVE-2026-109527","CVE-2026-109829","CVE-2026-109869","CVE-2026-109956","CVE-2026-110856","CVE-2026-110857","CVE-2026-110858","CVE-2026-110859","CVE-2026-111064","CVE-2026-111066","CVE-2026-111497","CVE-2026-112390","CVE-2026-112391","CVE-2026-112392","CVE-2026-112397","CVE-2026-112399","CVE-2026-112400","CVE-2026-112402","CVE-2026-112404","CVE-2026-112405","CVE-2026-112893","CVE-2026-112894","CVE-2026-112895","CVE-2026-112896","CVE-2026-112897","CVE-2026-112940","CVE-2026-114145"]},{"id":"RHSA-2026:92303","title":"Red Hat Security Advisory: multicluster engine for Kubernetes v2.8.12 security update","vulnerabilityIds":["CVE-2026-33818","CVE-2026-39822","CVE-2026-39834","CVE-2026-56853","CVE-2026-56858","CVE-2026-56859","CVE-2026-56860","CVE-2026-56862","CVE-2026-63209","CVE-2026-84304","CVE-2026-93748","CVE-2026-106445","CVE-2026-106446"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
