Prior to 0.19.1, site extractors interpolate page-derived image alt and src values, og:image values, and video descriptions into HTML strings without context-appropriate escaping, and buildExtractorResponse() returns this contentHtml without the main pipeline's DOM-based sanitization. The affected paths include src/extractors/x-article.ts, src/extractors/substack.ts, and src/extractors/youtube.ts. A malicious page or attacker-controlled content on a matching domain can inject event-handler attributes or javascript URLs that execute when a victim or downstream application renders the extracted HTML. This issue is fixed in version 0.19.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","score":8.2},"cwes":["CWE-79","CWE-116"],"references":["https://github.com/kepano/defuddle/commit/baf2eaef61d334ef595b28c89e5c5e89e52daf7f","https://github.com/kepano/defuddle/pull/326","https://github.com/kepano/defuddle/releases/tag/0.19.1","https://github.com/kepano/defuddle/security/advisories/GHSA-jg4p-g6xj-4qmf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-61824","score":0.0041,"percentile":0.3496,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jg4p-g6xj-4qmf","url":"https://osv.dev/vulnerability/GHSA-jg4p-g6xj-4qmf","summary":"Defuddle vulnerable to XSS via unescaped attribute interpolation in site extractors","modified":"2026-08-21T21:10:59.866904Z","packages":[{"ecosystem":"npm","name":"defuddle","purl":"pkg:npm/defuddle","ranges":["<0.19.1"],"fixed":["0.19.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
