What the vulnerability does

01Description

The AM LottiePlayer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via uploaded lottie files in all versions up to, and including, 3.5.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
