Schema Shortcode
Monthly
The Schema Shortcode plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability in the `itemscope` shortcode that allows authenticated attackers with contributor-level access or higher to inject arbitrary malicious scripts into pages. These injected scripts execute whenever any user accesses the affected page, potentially compromising visitor sessions and data. With a CVSS score of 6.4 and confirmed vulnerability through Wordfence intelligence, this represents a meaningful risk to WordPress sites using this plugin, though exploitation requires authenticated access rather than unauthenticated exploitation.
