CVE-2025-29771
March 14, 2025
HtmlSanitizer is a client-side HTML Sanitizer. Versions prior to 2.0.3 have a cross-site scripting vulnerability when the sanitizer is used with a "contentEditable" element to set the elements "innerHTML" to a sanitized string produced by the package. If the code is particularly crafted to abuse the code beautifier, that runs AFTER sanitation. The issue is patched in version 2.0.3.
