Name of the Vulnerable Software and Affected Versions Advanced Popups plugin for WordPress versions up to, and including, 1.1.1

Description The issue is due to missing or incorrect nonce validation on the metabox popup save() function, making it possible for unauthenticated attackers to save meta tags via a forged request if they can trick a site administrator into performing an action such as clicking on a link.

Recommendations For versions up to, and including, 1.1.1, consider disabling the metabox popup save() function until a patch is available to prevent exploitation. Restrict access to the plugin's functionality to minimize the risk of unauthorized meta tag modifications.
