{"apiVersion":"1.0","identifier":"CVE-2026-41067","description":"Astro is a web framework. Prior to 6.1.6, the defineScriptVars function in Astro-s server-side rendering pipeline uses a case-sensitive regex /<\\/script>/g to sanitize values injected into inline <script> tags via the define:vars directive. HTML parsers close <script> elements case-insensitively and also accept whitespace or / before the closing >, allowing an attacker to bypass the sanitization with payloads like </Script>, </script >, or </script/> and inject arbitrary HTML/JavaScript. This vulnerability is fixed in 6.1.6.","publishedAt":"2026-04-24T17:16:21","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41067","cvssScore":6.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","epssProbability":0.00189,"riskScore":0.62,"affectedProduct":"Astro","affectedVersions":"<6.1.6","vulnerabilityType":"Package","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41067","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41067","en":"https://www.redsauce.net/en/cves/CVE-2026-41067","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41067","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41067","de":"https://www.redsauce.net/de/cves/CVE-2026-41067","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41067","el":"https://www.redsauce.net/el/cves/CVE-2026-41067"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41067"}}
