EmbedPress – Embed PDF, 3D Flipbook, Social Feeds, Google Docs, Vimeo, Wistia, YouTube Videos, Audios, Google Maps in Gutenberg Block & Elementor < 4.1.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'provider_name'

Description

The EmbedPress – Embed PDF, 3D Flipbook, Social Feeds, Google Docs, Vimeo, Wistia, YouTube Videos, Audios, Google Maps in Gutenberg Block & Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘provider_name parameter in all versions up to, and including, 4.1.3 due to insufficient input sanitization and output escaping. 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.
