Name of the Vulnerable Software and Affected Versions EmbedPress – Embed PDF, 3D Flipbook, Social Feeds, Google Docs, Vimeo, Wistia, YouTube Videos, Audios, Google Maps in Gutenberg Block & Elementor plugin for WordPress versions up to, and including, 4.1.3

Description The issue is related to Stored Cross-Site Scripting via the provider name parameter due to insufficient input sanitization and output escaping. This allows 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.

Recommendations For versions up to, and including, 4.1.3, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the provider name parameter to minimize the risk of exploitation.
