    Hello, I noticed a Cross-site Scripting (XSS) – DOM weakness, as there is a vulnerable DOMPurify library used.

    The identified library DOMPurify, version 2.0.12 is vulnerable and gets called in /wp-content/plugins/podlove-web-player/web-player/embed.js?ver=5.7.3

    Cure53 DOMPurify before 2.0.17 allows mutation XSS. This occurs because a serialize-parse roundtrip does not necessarily return the original DOM tree, and a namespace can change from HTML to MathML, as demonstrated by nesting of FORM elements.

    Please upgrade to the latest version of DOMPurify v3.0.8
