{"apiVersion":"1.0","identifier":"CVE-2026-8630","description":"justhtml before 1.12.0 (versions <= 1.11.0) contains a mutation cross-site scripting (mXSS) vulnerability in the serialization of raw-text elements such as <style> and <script>. When a DOM tree is processed by sanitize_dom() using a custom policy that keeps these elements, text nodes inside them are serialized literally without escaping, allowing attacker-controlled text containing the matching closing tag sequence to break out of the raw-text context and inject arbitrary HTML into the serialized output. The default sanitization policy is not affected because it drops the contents of style and script.","publishedAt":"2026-08-23T14:16:55","lastModifiedAt":"2026-08-26T19:17:20","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-8630","cvssScore":6.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","epssProbability":0.00188,"riskScore":0.62,"affectedProduct":"justhtml","affectedVersions":"<1.12.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-8630","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-8630","en":"https://www.redsauce.net/en/cves/CVE-2026-8630","fr":"https://www.redsauce.net/fr/cves/CVE-2026-8630","pt":"https://www.redsauce.net/pt/cves/CVE-2026-8630","de":"https://www.redsauce.net/de/cves/CVE-2026-8630","sk":"https://www.redsauce.net/sk/cves/CVE-2026-8630","el":"https://www.redsauce.net/el/cves/CVE-2026-8630"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-8630"}}
