CVE-2024-3818

Name of the Vulnerable Software and Affected Versions The Essential Blocks – Page Builder Gutenberg Blocks, Patterns & Templates plugin for WordPress versions up to, and including, 4.5.9

Description The issue is related to Stored Cross-Site Scripting via the plugin's "Social Icons" block due to insufficient input sanitization and output escaping on user-supplied attributes. 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, 4.5.9, update to a version later than 4.5.9 to resolve the issue. As a temporary workaround, consider restricting access to the "Social Icons" block until a patch is available.
