Summary

The Schema App Structured Data plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content through the 'Remove Microdata' Output Filter in all versions up to and including 2.3.2 due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary web scripts that execute when a user accesses an injected page.

Risk Assessment

Injected scripts may execute in users' and administrators' browsers, leading to session or data theft. Exploitation requires the 'Remove Microdata' option to be enabled and the malicious comment to be approved by an administrator.

Recommendation

Update the plugin to a version newer than 2.3.2 if available, or disable the 'Remove Microdata' option. Review comments before approving them.
