Name of the Vulnerable Software and Affected Versions The Schema App Structured Data plugin for WordPress versions up to, and including, 2.2.0

Description The issue is due to missing or incorrect nonce validation on the MarkUpdate function, making it possible for unauthenticated attackers to update and delete post metadata via a forged request. This can be achieved if an attacker can trick a site administrator into performing an action, such as clicking on a link.

Recommendations For versions up to, and including, 2.2.0, update to a version that includes the fix for the missing or incorrect nonce validation on the MarkUpdate function. As a temporary workaround, consider restricting access to the MarkUpdate function until a patch is available.
