Una vulnerabilidad de tipo cross-site scripting en Modern Events Calendar Lite versiones anteriores a 6.3.0, permite a un atacante remoto autenticado inyectar un script arbitrario por medio de vectores no especificados

The Modern Events Calendar Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an unknown parameter in versions up to, and including, 6.2.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
