CVE-2026-61824: Defuddle vulnerable to XSS via unescaped attribute interpolation in site extractors

August 21, 2026

An Improper Neutralization of Input During Web Page Generation issue in the site extractor component allows an attacker-controlled attribute value to be injected into output HTML without escaping. An attacker who crafts a malicious HTML page or controls content on a matching domain can execute arbitrary scripts when a victim processes the page, resulting in Cross-Site Scripting (XSS). This affects defuddle through 0.19.0 and has been patched in version 0.19.1.
