Technical summary

Defuddle prior to version 0.19.1 is vulnerable to HTML injection attacks due to improper escaping of user-derived content. An attacker can inject event-handler attributes or JavaScript URLs that execute when a victim or downstream application renders the extracted HTML. The affected product context includes site extractors that interpolate page-derived image alt and src values, og:image values, and video descriptions into HTML strings without context-appropriate escaping.
