Users should monitor the vendor's advisory for updates regarding remediation. Until a fix is released, restrict administrator access to trusted users only and consider limiting multi-site usage or configurations where unfiltered_html is disabled if possible. Review and sanitize admin input manually where feasible to reduce risk.
Description
The WP Google Ad Manager Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
