CVE-2026-61824

Name of the Vulnerable Software and Affected Versions Defuddle versions prior to 0.19.1

Description Site extractors interpolate page-derived image alt and src values, og:image values, and video descriptions into HTML strings without context-appropriate escaping. Additionally, the buildExtractorResponse() function returns this content without the main pipeline's DOM-based sanitization. This allows a malicious page or attacker-controlled content on a matching domain to inject event-handler attributes or javascript URLs that execute when a victim or downstream application renders the extracted HTML. The affected paths include src/extractors/x-article.ts, src/extractors/substack.ts, and src/extractors/youtube.ts.

Recommendations Update to version 0.19.1.
