Cross site scripting (XSS) vulnerability using url preview in Misskey

Misskey is an open source, decentralized social media platform. In versions prior to 13.3.2 the URL preview function is subject to a cross site scripting vulnerability due to insufficient URL validation. Arbitrary JavaScript is executed when a malicious URL is loaded in the `View in Player` or `View in Window` preview. This has been fixed in version 13.3.2. Users are advised to upgrade. Users unable to upgrade should avoid usage of the `View in Player` or `View in Window` functions.
