{"id":"CVE-2026-92106","published":"2026-09-25T10:17:08.263","lastModified":"2026-09-25T13:22:04.673","description":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in dashbitco lazy_html allows mutation XSS via a parse and serialize round-trip of attacker-supplied HTML.\n\nLazyHTML.to_html/2 and LazyHTML.Tree.to_html/2 decide whether to escape an element's text from its tag name alone. A style or script element inside SVG or MathML foreign content is parsed with character references decoded, but is serialized as an HTML raw-text element, so its text is emitted unescaped. Encoded markup such as &lt;/style&gt;&lt;img src=x onerror=...&gt; inside <svg><style> therefore closes the element on re-parse and becomes live markup. Applications that parse untrusted HTML with lazy_html, filter the document or tree, and serialize it for display are affected, since the payload is a plain text node that no element or attribute filter sees.\n\nThis issue affects lazy_html: from 0.1.0 before 0.1.13.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://cna.erlef.org/cves/CVE-2026-92106.html","tags":[]},{"url":"https://github.com/dashbitco/lazy_html/commit/1dee15746c024916b3110af8b168c2f3b3065fbd","tags":[]},{"url":"https://github.com/dashbitco/lazy_html/commit/f32c7fd6223225b68bc8691c78b6d4a77972f1d5","tags":[]},{"url":"https://github.com/dashbitco/lazy_html/security/advisories/GHSA-8rqp-v692-v82q","tags":[]},{"url":"https://osv.dev/vulnerability/EEF-CVE-2026-92106","tags":[]}],"exploitRefs":[{"url":"https://github.com/dashbitco/lazy_html/commit/1dee15746c024916b3110af8b168c2f3b3065fbd","tags":[]},{"url":"https://github.com/dashbitco/lazy_html/commit/f32c7fd6223225b68bc8691c78b6d4a77972f1d5","tags":[]},{"url":"https://github.com/dashbitco/lazy_html/security/advisories/GHSA-8rqp-v692-v82q","tags":[]}],"hasPoc":true,"ai":null}
