CVE-2019-25225: sanitize-html is vulnerable to XSS through incomprehensive sanitization
(updated )
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.
