{"apiVersion":"1.0","identifier":"CVE-2026-8445","description":"justhtml versions <= 1.11.0 (fixed in 1.12.0) do not sufficiently escape HTML-significant characters (angle brackets) in text nodes when converting a parsed document to Markdown via to_markdown(). While a small set of Markdown metacharacters are escaped, characters such as < and > are preserved, so untrusted input that is safe in to_html() — including entity-decoded text (e.g. <script>) or text from RCDATA/RAWTEXT-parsed elements like <title>, <textarea>, <noscript>, and <plaintext> — can be emitted as raw HTML in the Markdown output, enabling a sanitizer bypass and potential cross-site scripting when that output is rendered.","publishedAt":"2026-08-23T14:16:54","lastModifiedAt":"2026-08-26T17:10:53","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-8445","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00381,"riskScore":1.01,"affectedProduct":"justhtml","affectedVersions":"<=1.11.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-8445","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-8445","en":"https://www.redsauce.net/en/cves/CVE-2026-8445","fr":"https://www.redsauce.net/fr/cves/CVE-2026-8445","pt":"https://www.redsauce.net/pt/cves/CVE-2026-8445","de":"https://www.redsauce.net/de/cves/CVE-2026-8445","sk":"https://www.redsauce.net/sk/cves/CVE-2026-8445","el":"https://www.redsauce.net/el/cves/CVE-2026-8445"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-8445"}}
