FKIE_CVE-2026-44990

Vulnerability from fkie_nvd - Published: 2026-06-12 21:16 - Updated: 2026-09-10 13:20
Summary
ApostropheCMS is an open-source Node.js content management system, and sanitize-html provides a simple HTML sanitizer with a clear API. Under the default configuration, versions of `sanitize-html` prior to 2.17.4 can turn attacker-controlled content inside a disallowed `xmp` element into live HTML or JavaScript. This is a sanitizer bypass in the default `disallowedTagsMode: 'discard'` path and can lead to stored XSS in applications that render sanitized output back to users. Version 2.17.4 patches the issue.

This is a sanitizer bypass in the default `disallowedTagsMode: \u0027discard\u0027` path and can lead to stored XSS in applications that render sanitized output back to users.
