Description
The EmbedPress – Embed PDF, Google Docs, Vimeo, Wistia, Embed YouTube Videos, Audios, Maps & Embed Any Documents in Gutenberg & Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'embedpress_calendar' shortcode in all versions up to, and including, 3.9.14 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.
