Neutralización inadecuada de la entrada durante la vulnerabilidad de generación de páginas web ('Cross-site Scripting') en Joseph C Dolson Mi calendario permite almacenar XSS. Este problema afecta a Mi calendario: desde n/a hasta 3.4.23.

The My Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 3.4.23 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with, contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
