Description
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.
CWEs
- CWE-79 · Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
