Defuddle vulnerable to XSS via unescaped attribute interpolation in site extractors
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## Summary
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.
## Impact
This vulnerability allows for Cross-Site Scripting (XSS) execution without needing to compromise external websites. Affected consumers include:
- Obsidian Web Clipper,
- web services serving the parsed output directly as HTML, and
- any downstream application rendering the unsanitized HTML results
## Patch
This issue has been patched in defuddle version 0.19.1. Users are encouraged to update to the latest release.
