GHSA-qhxp-v273-g94h
sanitize-html is vulnerable to XSS through incomprehensive sanitization
Quick fix
GHSA-qhxp-v273-g94h — sanitize-html: upgrade to the fixed version with the command below.
npm install sanitize-html@2.0.0-betaDetails
`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.
