This can result in a denial-of-service (DoS) condition or, under certain conditions, escape the sandboxed environment intended to restrict code execution. The vulnerability stems from insufficient prototype access checks in the sandbox’s executor logic, particularly in the handling of JavaScript function objects returned.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","score":7,"severity":null}],"references":["https://gist.github.com/Hagrid29/9df27829a491080f923c4f6b8518d7e3","https://github.com/nyariv/SandboxJS/issues/31","https://www.npmjs.com/package/@nyariv/sandboxjs","https://www.vulncheck.com/advisories/nyariv-sandboxjs-prototype-pollution-sandbox-escape-dos"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-23278","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jul 31, 2025, 2:59:35 PM","dateUpdated":"Oct 8, 2026, 3:21:18 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
