- Summary
- html-sanitizer allows arbitrary HTML present after sanitization because of unicode normalization
- Details
-
html-sanitizer is an allowlist-based HTML cleaner. If using
keep_typographic_whitespace=False(which is the default), the sanitizer normalizes unicode to the NFKC form at the end. Some unicode characters normalize to chevrons; this allows specially crafted HTML to escape sanitization. The problem has been fixed in 2.4.2. - References
