Administrators should disable the 'Remove Microdata' option to prevent exploitation. Additionally, avoid approving untrusted comments until a fix is available. Monitor vendor advisories for updates regarding a patch or official remediation.
Description
The Schema App Structured Data plugin for WordPress up to version 2.3.2 contains a stored cross-site scripting (XSS) vulnerability. This flaw arises from insufficient input sanitization and output escaping in the 'Remove Microdata' output filter. An unauthenticated attacker can inject malicious scripts via comment content, which execute when users view the affected pages. Exploitation requires that an administrator has enabled the 'Remove Microdata' option and approved the malicious comment.
