WordPress · Wp Google Ad Manager Plugin · CVE-2026-1399
**Name of the Vulnerable Software and Affected Versions**
WP Google Ad Manager Plugin versions prior to 1.1.1
**Description**
The WP Google Ad Manager Plugin for WordPress is susceptible to Stored Cross-Site Scripting through admin settings. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts into pages. These scripts execute when a user accesses the injected page. This issue only impacts multi-site installations and those where unfiltered html has been disabled.
**Recommendations**
Update the WP Google Ad Manager Plugin to version 1.1.1 or later.
