Summary
sanitize-html is vulnerable to XSS through incomprehensive sanitization
Details

sanitize-html prior to version 2.0.0-beta is vulnerable to Cross-site Scripting (XSS). The sanitizeHtml() function in index.js does not sanitize content when using the custom transformTags option, which is intended to convert attribute values into text. As a result, malicious input can be transformed into executable code.

Severity ?
6.1 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
