CVE-2019-25225: Apostrophecms Sanitize-Html

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

`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.
