CVE-2025-29771 – HtmlSanitizer vulnerable to XSS when used with contentEditable

https://notcve.org/view.php?id=CVE-2025-29771

14 Mar 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. • https://github.com/jitbit/HtmlSanitizer/commit/af6d2a78877e7277cd01c825b7fb50edb5956963 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
