Leyka <= 3.30.3 - Authenticated (Administrator+) Stored Cross-Site Scripting

The Leyka plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 3.30.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. NOTE: The problem was communicated to the developer on May 30, 2023, and was patched via a hot-fix in version 3.30.3 instead of a new release being rolled out.
