CVE-2026-30830 · Defuddle: XSS via unescaped string interpolation in _findContentBySchemaText image tag
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Defuddle cleans up HTML pages. Prior to version 0.9.0, the _findContentBySchemaText method in src/defuddle.ts interpolates image src and alt attributes directly into an HTML string without escaping. An attacker can use a " in the alt attribute to break out of the attribute context and inject event handler. This issue has been patched in version 0.9.0.
