{"id":"CVE-2026-61824","summary":"Defuddle:  XSS via unescaped attribute interpolation in site extractors","details":"Defuddle cleans up HTML pages. 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.","aliases":["GHSA-jg4p-g6xj-4qmf"],"modified":"2026-08-23T03:49:32.068414129Z","published":"2026-08-21T20:12:53.225Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-116","CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61824.json"},"references":[{"type":"WEB","url":"https://github.com/kepano/defuddle/releases/tag/0.19.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61824.json"},{"type":"ADVISORY","url":"https://github.com/kepano/defuddle/security/advisories/GHSA-jg4p-g6xj-4qmf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61824"},{"type":"FIX","url":"https://github.com/kepano/defuddle/commit/baf2eaef61d334ef595b28c89e5c5e89e52daf7f"},{"type":"FIX","url":"https://github.com/kepano/defuddle/pull/326"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kepano/defuddle","events":[{"introduced":"0"},{"fixed":"baf2eaef61d334ef595b28c89e5c5e89e52daf7f"},{"fixed":"6c39f0959a2f566469a93a190b50e4b34bcf52c4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.19.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["0.19.0","0.18.1","0.18.0","0.17.0","0.16.0","0.15.0","0.14.0","v0.13.0","0.13.0","0.12.0","0.11.0","0.10.0","0.9.0","0.8.0","0.7.0","0.6.6","0.6.5","0.6.4","0.6.3","0.6.2","0.6.1","0.6.0","0.5.4","0.5.3","0.5.2","0.5.1","0.5.0","0.4.0","0.3.8","0.3.7","0.3.6","0.3.4","0.3.3","0.3.2","0.3.1","0.3.0","0.2.4","0.2.3","0.2.2","0.2.1","0.2.0","0.1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61824.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N"}]}
