Name of the Vulnerable Software and Affected Versions The Schema & Structured Data for WP & AMP plugin for WordPress versions up to, and including, 1.29

Description The issue is related to Stored Cross-Site Scripting via the plugin's "How To" and "FAQ" Blocks 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, 1.29, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the "How To" and "FAQ" Blocks to minimize the risk of exploitation. Additionally, restrict contributor-level access and above to prevent authenticated attackers from injecting arbitrary web scripts.
