CVE-2026-1575: Jeric Izon Schema Shortcode

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The Schema Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `itemscope` shortcode in all versions up to, and including, 1.0 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.
