CVE-2026-61824Network attack vectorHinoki check available

XSS via unescaped site-extractor attribute interpolation

Published Aug 21, 2026 · Updated Aug 21, 2026

Cross-site scripting in Defuddle before 0.19.1 allows remote attackers to execute scripts through attacker-controlled page content. The Substack, X Article, and YouTube extractors interpolate page-derived attributes and descriptions into HTML strings without escaping, and buildExtractorResponse() returns that HTML without the main DOM sanitizer. Exploitation requires a victim or downstream application to process content matching an affected extractor and render the resulting HTML, exposing that renderer's data and DOM to injected script.
